German Forces Surge Onto Baltic Island In First-Of-Its-Kind NATO Drill

18 September 2026 at 20:12

Swedish and German forces are conducting what appears to be the first joint rehearsal of their rapid-reinforcement plans for the Baltic island of Gotland. The exercise is another step in Sweden’s defense planning for an island whose position in the middle of the Baltic gives it an outsized strategic importance for controlling access, protecting the Baltic states, and maintaining NATO’s freedom of movement in a region where Russian military activity remains a persistent concern.

The exercise, Silver Wotan 2026, running between September 14-23, brings together Swedish and German forces across the land, maritime, and air domains. The scenario is built around a Swedish request for allied assistance, with German forces moving personnel and equipment across the Baltic before integrating with Swedish units already defending the island. The operation is testing the entire process of getting allied combat power to Gotland, protecting it during the movement to Visby, and rapidly incorporating it into the island’s existing defensive network.

The strategic importance of Gotland has grown considerably following Sweden’s accession to NATO in March 2024, which was a direct response to the full-scale Russian invasion of Ukraine.

Located approximately halfway between mainland Sweden and the Baltic states, the island occupies a central position in the Baltic Sea, close to the maritime approaches to the Gulf of Finland and within reach of the Russian exclave of Kaliningrad. Its location gives forces operating from Gotland a potentially significant position from which to conduct surveillance, air defense, and maritime operations, while also making the island an important part of the wider network connecting NATO’s northern and eastern members.

At the same time, Gotland sits within an extremely complex littoral environment, where shallow waters, islands, narrow maritime approaches, and the proximity of multiple states can make both offensive operations and defensive planning more difficult. The region has also been shaped by longstanding Swedish concerns about Russian clandestine activity, including intelligence gathering and other forms of covert or deniable activity. The complexity of the Baltic operating environment can make such activities harder to detect and attribute, adding another layer of uncertainty alongside the more conventional military challenges facing the region.

Geography has long made Gotland important to Swedish defense planning, but its significance has taken on a broader dimension since Sweden joined the alliance. NATO has described the island as strategically important to its freedom of maneuver in the Baltic, while Swedish officials have highlighted its potential role as a hub for military operations and logistics in the region.

The current exercise is designed around the practical difficulties of reinforcing such a position.

Military equipment is being transported by sea to Visby, Gotland’s principal port, including by commercial ferry. In Visby, Swedish and German personnel are securing the harbor and conducting the reception of the arriving force. Among the equipment being moved are air defense systems, while Swedish forces are also operating coastal defense systems armed with anti-ship missiles.

Meanwhile, publicly available flight-tracking data showed German Luftwaffe transport aircraft, including at least one Airbus A400M airlifter, apparently involved in the effort. The commercial airport at Visby has long also been used for military activities related to Gotland and the wider Baltic region.

The movement is supported by Swedish and German naval forces and other aircraft, creating a scenario in which the maritime transit, protection of the port, air operations, and subsequent movement of troops and equipment ashore all form part of the same military problem. Once ashore, the arriving forces have to be moved into position and integrated with Swedish units already responsible for defending the island.

The Swedish Gotland Regiment, P 18, provides the core of the island’s permanent military presence. The regiment, Sweden’s youngest and smallest, has been rebuilding its capabilities since Sweden began expanding its military presence on Gotland. Its forces form the basis of the ground-defense structure into which allied reinforcements would be incorporated.

Swedish coastal defense capabilities are another important element of the drill. Land-based anti-ship missiles provide the island with a means of threatening hostile surface vessels operating in the surrounding waters, giving the defense of Gotland a direct connection to the wider maritime battle for the Baltic. During Silver Wotan, Swedish and German forces are also conducting anti-surface warfare activities alongside the broader reinforcement operation.

Germany is contributing more than 500 troops to the exercise, part of approximately 2,000 Bundeswehr personnel involved, including elements from the army, navy, and air force. The German Luftwaffe has deployed Panavia Tornado aircraft for surveillance, while German naval forces are participating in the maritime component, and German ground personnel are involved in the reinforcement and security activities on Gotland.

The exercise scenario is particularly relevant against the backdrop of Russia’s continuing military presence in the Baltic region.

Russia maintains major military infrastructure in Kaliningrad, including naval, air, missile, and air defense capabilities, while the Russian Baltic Fleet operates from bases in the region. Kaliningrad’s position between Poland and Lithuania gives Moscow a significant military foothold inside the NATO area, while Russian forces and military infrastructure elsewhere along the Baltic add to the complexity of operating and reinforcing allied territory in the region.

The security environment around the Baltic has also deteriorated considerably since Russia’s full-scale invasion of Ukraine. NATO has increased its surveillance and military activity in the region, including the launch of Baltic Sentry in January 2025 following a series of incidents involving critical undersea infrastructure. The alliance has subsequently expanded efforts to monitor maritime activity and protect infrastructure and sea lines of communication.

A picture taken on February 4, 2025 shows a Helicopter 15 (HKP15) (L) on the flight deck of patrol ship HMS Carlskrona (P04) on open water near Karlskrona, Sweden, as part of the NATO Baltic Sea patrol mission, the Baltic Sentry, aimed to secure critical underwater infrastructure. The patrol ship HMS Carlskrona (P04) set off from the naval port in Karlskrona on February 4, 2025 to become part of NATO's Baltic Sentry operation as one of several Swedish ships that are part of Standing NATO Maritime Group One (SNMG1). This is the first time the ship has hoisted the NATO flag on board. The purpose of NATO's Baltic Sentry operation is to demonstrate presence and secure critical underwater infrastructure.

Swedish authorities have stressed that Silver Wotan was planned in advance and is not being conducted in response to a specific imminent Russian threat. The exercise nonetheless reflects the operational environment in which Swedish and NATO planners now have to consider the possibility that maritime and air movements across the Baltic could be monitored, disrupted, or contested.

The exercise also builds on a series of increasingly large Swedish-led activities designed to test the reception of allied forces on Swedish territory. During Aurora 26 earlier this year, more than 18,000 troops from 13 countries participated in operations across Sweden, including the deployment of allied forces to Gotland alongside the Gotland Regiment and Swedish Home Guard. NATO described that activity as an emergency deployment intended to test the reinforcement of the island.

Silver Wotan places a more concentrated emphasis on the Swedish-German relationship and on the movement of an allied force into the island’s existing defensive structure.

Germany’s participation is also consistent with its growing military role in the Baltic and along NATO’s northeastern flank. Berlin is already providing forces for NATO’s forward defense in Lithuania and has increasingly emphasized the ability to move German forces rapidly across northern Europe in support of allied operations.

For Sweden, meanwhile, Gotland has become one of the clearest examples of how NATO membership has changed the country’s defense planning. The island remains a Swedish responsibility, but its location means that what happens there has consequences well beyond Sweden’s territorial defense.

A defended and adequately supplied Gotland provides NATO with a strategically positioned base for surveillance and defensive operations in the Baltic, while the ability to reinforce it demonstrates that the alliance can maintain access to the island even as the surrounding maritime and air environment becomes more contested.

The exercise comes as European allies are being forced to plan for a NATO in which the United States may provide less of the conventional military weight it has supplied for decades. The Pentagon is reviewing the size and posture of U.S. forces in Europe, including the forces and capabilities Washington would make available in a European crisis, while NATO’s top commander has said further U.S. troop withdrawals should be expected as European allies build up their own conventional capabilities.

At the same time, the alliance now describes Russia as its most significant and direct security threat, citing military activity alongside airspace violations, sabotage, cyber operations, and other forms of hybrid pressure. There are also growing concerns that Russia could try something in the Baltics, while it continues to step up its gray-zone activities regardless. NATO officials have warned that Russia could rebuild enough military capacity to pose a more serious conventional challenge to the alliance before the end of the decade.

There are escalating warnings from Poland that Russia is preparing to widen its war against Ukraine, with "accidental" missile and drone strikes on NATO territory.

Such a move – Russia falsely claiming air strikes that hit NATO allies happened by accident – would be designed to…

For Sweden and Germany, the Silver Wotan exercise is a practical test of how quickly European forces can reinforce and defend one of the Baltic’s most strategically important positions. As the security environment grows more contested and Europe prepares for a future in which U.S. forces may not be as readily available, the ability to move allied combat power across the region and integrate it into existing defenses is becoming an increasingly important part of NATO’s deterrence.

Marine Colonel Who Led Mideast Combat Deployment Wants His Own Drone Boats

18 September 2026 at 19:01

The officer who led the 31st Marine Expeditionary Unit (MEU) on its recent combat deployment to the Middle East told us he needs his own uncrewed surface vessels (USVs) on future deployments. Operationalizing USVs is an area where the Marines are lagging behind. In particular, he wants the ability to send USVs forward to reconnoiter potential highly-contested beach landing areas, a mission largely assumed by the Navy.

As we have frequently reported, the military use of USVs is now proliferating around the globe at an increasing rate. Ukraine has employed sea drones to devastating effect against Russia’s Black Sea Fleet vessels and facilities, forcing the general evacuation of Russian naval assets from occupied Crimea to bases in Russia proper. During Operation Epic Fury, the U.S. used them for the first time in combat, as one-way attack weapons against Iranian targets, to hunt for mines, and for a search and rescue operation to locate the crew of an AH-64 Apache helicopter downed by Iran, as well as general broad-area surveillance and awareness. China is investing heavily in the space, as well, along with many other navies around the globe, both friend and foe.

The following video shows the first U.S. use of a USV as a kamikaze weapon.

“There was a lot in theater that were being used, but it wasn’t something that we went out with,” Col. Chris P. Niedziocha told us when asked if the 31st MEU deployed with USVs. He then answered in the affirmative in response to a question about if MEUs need sea drones on future deployments. He said it is part of the “explosion in robotics and autonomy” being used in combat.

“These systems are incredibly useful and capable,” explained Niedziocha, now director of the USMC Expeditionary Warfare School. “And you say, ‘Hey, you know, [in] the next war, if the first thing you’re putting through the breach isn’t a robot, something’s wrong. You say never send a Marine someplace you haven’t sent a bullet. I think the new way is [you] never want to send a Marine someplace you haven’t already sent a robot. So yeah, we’re embracing [the technology] and we’re not leaders. We’re fast followers in that regime.”

Asked for specific use cases he sees for USVs, the colonel talked about using them before putting Marines ashore.

“I can tell you if you’re doing an amphibious operation, you want to understand what’s waiting beneath the surface in the water column,” Niedziocha noted. “So something can go either with a side-looking sonar array or even forward-looking to demonstrate that there’s nothing there, and the hydrography and bathymetry is what you… need for the operation to be successful.”

Hydrography measures “the shape and features of the shoreline; the characteristics of tides, currents, and waves; and the physical and chemical properties of the water itself,” according to NOAA. Bathymetry, which is part of that, focuses on mapping the depths and shapes of underwater terrain.

These functions are critical for mine detection and determining whether there are man-made or natural obstacles that would impede landing operations. While these missions are largely being performed by the Navy, including with USVs, the Marines are moving toward making that an organic capability. Recently, the Marines announced they were testing a counter-mine USV system. The evaluation was conducted late last month at Camp Pendleton by the Program Manager Combat Support Systems (PM CSS) Explosive Hazard Defeat Team.

The test of the USV was “in response to a littoral capability gap,” according to the media release. “The solution: seek a commercial USV solution that is equipped with integrated autonomous driving and payloads that consist of Sonar, Forward-Looking Infrared (FLIR) cameras, Line of Sight (LOS) Communications and Acoustic Communications (AComms).”

This was part of the overall effort to develop “solutions that enable increased standoff for Marines to detect, investigate and neutralize threats,” the release added. “The innovation of Explosive Ordnance Disposal (EOD) and Littoral Explosive Ordnance Neutralization (LEON) systems will provide Marine EOD Technicians with the confidence to operate in contested environments while preserving combat power, increasing operational reach, and minimizing exposure to explosive threats.”

LEON is a so-called system of systems, using a remotely operated vehicle, diver equipment, an unmanned underwater vehicle (UUV), a USV, and an Amphibious Unmanned Ground Vehicle to enable “EOD to confirm and mark hazards and obstacles from very shallow water to the beach zone,” the media release added.

While unmanned systems have long been part of EOD operations, “we’re expanding that into maritime systems that allow more endurance and less risk for operators,” said Chief Warrant Officer 2 Alfredo Andrade, officer in charge, Explosive Ordnance Disposal Company, 7th Engineer Support Battalion (ESB). “Some of the conflicts that we are engaged in take a toll on the force, and surging in new forces is costly. It turns into a logistical problem. To preserve the safety and the health of the forces… the USV and the [LEON] program exist to ensure that we have readily available combat power.”

In late August at Camp Pendleton, the PM CSS Explosive Hazard Defeat Team tested an Unmanned Surface Vessel in response to a littoral capability gap. The solution: seek a commercial USV solution that is equipped with integrated autonomous driving and payloads that consist of Sonar, Forward-Looking Infrared (FLIR) cameras, Line of Sight (LOS) Communications and Acoustic Communications (AComms). The LEON System of Systems (SOS) consists of five increments of capabilities to include a Remotely Operated Vehicle, diver equipment, Unmanned Underwater Vehicle, Unmanned Surface Vehicle, and an Amphibious Unmanned Ground Vehicle. LEON enables EOD to confirm and mark hazards and obstacles from very shallow water to the beach zone. (PAE Marine Corps photo by Kristiana Gehly)

While Niedziocha didn’t address USVs for offensive combat roles, the Marines have evaluated them for that use as well as for logistics, among other functions.

There have been many other tests, as well. Including one just this summer at RIMPAC. These trials saw the launch and recovery of one of Splash Industries’ Typhoon USVs aboard the USS Essex. The ‘Gator Navy’ of amphibious assault vessels that haul Marines and their kit around the oceans is uniquely suited to act as USV motherships. Their well decks allow for easy deployment and recovery of USVs of many sizes and capabilities near seamlessly. So it won’t be surprising if these vessels and the Marines aboard them quickly become staples in the Pentagon’s USV playbook.

— Ivan Avanesov (@i_vanesov) July 14, 2026

Still, the Marines have a long way to go to catch up to how these systems are already being used.

The Houthi rebels of Yemen actually pioneered the operational use of kamikaze USVs years ago and Ukraine has led the way in advancements of these systems. They first employed them as kamikaze weapons, but then added machine guns and rockets and later missiles, which were used to shoot down Russian helicopters and jets. Ukraine has also used them to launch first-person view (FPV) and bomber drone attacks as well as deliver uncrewed ground vehicles (UGVs) into enemy territory. Last week, Ukraine claimed to have attacked a Russian USV with a USV, marking another first.

You can see that engagement in the following video.

Having recently returned from a six-month deployment that saw the Marine Corps’ first use of its Expeditionary Advanced Base Operations (EABO) concept in a combat setting during the fight against Iran, Niedziocha has a good sense of the realities of modern warfare. His Marines operated forward arming and refueling points (FARPs) for various aircraft in combat for the first time and set up remote sensing locations.

That a commander like him sees value in USVs is a good sign for progress in the development of these systems.

Japan Opens The Door To Acquiring Nuclear-Powered Submarines

18 September 2026 at 17:36

Japan has said it is keeping the door open to acquiring nuclear-powered submarines, a potentially major shift for a country whose submarine force has historically relied exclusively on conventional propulsion. Defense Minister Shinjiro Koizumi confirmed recently that Tokyo is not ruling out nuclear-powered submarines as it considers the future requirements of the Japan Maritime Self-Defense Force (JMSDF).

Should Japan ultimately pursue the capability, it would join an exclusive group of nations operating nuclear-powered submarines. China, France, India, Russia, the United Kingdom, and the United States are currently the only countries with nuclear-powered submarines in active service. Brazil is already working to join the club, while Australian and South Korean nuclear-powered submarine plans are somewhat longer-term.

Japan’s submarine fleet is already regarded as among the most capable conventionally powered forces, and is very much at the forefront of advanced naval propulsion technologies. Even with that considerable expertise, however, developing and sustaining a nuclear propulsion capability would represent a huge challenge, requiring expertise and infrastructure far beyond those needed to build Japan’s existing conventionally powered submarines.

Koizumi’s comments do not represent a decision to acquire nuclear-powered submarines, nor do they indicate that Japan has begun a procurement program. They do, however, mark a significant evolution in the country’s public debate over submarine propulsion and point to a growing willingness within the Japanese defense establishment to consider capabilities that were previously largely outside the mainstream of defense planning.

Currently, Japan operates one of the world’s most capable conventional submarine fleets, centered on increasingly sophisticated diesel-electric boats equipped with air-independent propulsion and advanced lithium-ion batteries. These submarines are well suited to operations around Japan and the country’s surrounding waters.

The JMSDF currently operates 22 conventionally powered submarines, maintaining the force structure established in the 2010s while progressively replacing older boats with the more capable Taigei class. Five Taigei class submarines are now in JMSDF service, with additional boats in the pipeline.

The first-of-class Taigei was launched on October 14, 2020, at the Mitsubishi Heavy Industries (MHI) shipyard in the city of Kobe, in the western prefecture of Hyogo. Japan Maritime Self-Defense Force

Nuclear propulsion, however, would offer substantially greater endurance and sustained underwater speed, allowing Japanese submarines to conduct longer-range operations across the broader Western Pacific with minimal support. This is a requirement that is becoming increasingly relevant as Tokyo’s strategic focus expands beyond its immediate maritime approaches.

China’s rapidly expanding naval force, including its growing submarine fleet and increasingly distant maritime operations, is forcing Tokyo to consider how it would monitor and potentially counter Chinese forces farther from the Japanese archipelago. A nuclear-powered attack submarine could remain submerged for extended periods without the endurance limitations imposed by conventional propulsion, making it particularly useful for long-range surveillance, tracking, and sea-denial missions.

Japan’s debate is also unfolding alongside a significant development in neighboring South Korea. Seoul has confirmed plans to develop a new class of nuclear-powered submarines, a move that could add further momentum to an emerging undersea competition in Northeast Asia. South Korea’s decision is particularly relevant to Tokyo because it demonstrates that nuclear propulsion is no longer merely a theoretical capability for U.S. allies in the region. While the missions and strategic priorities of the Japanese and South Korean navies are different, both countries face the challenge of operating in waters increasingly contested by China and North Korea.

The development could also create new opportunities for Japan to work more closely with Australia and the other AUKUS partners. Australia is in the process of acquiring its own conventionally armed, nuclear-powered submarine capability under AUKUS Pillar I, with U.S. and U.K. nuclear-powered submarines also scheduled to operate from Australia. Japan has separately been identified as a potential partner for AUKUS Pillar II, which covers advanced capabilities and technology cooperation.

A Japanese decision to pursue SSNs could eventually create a much deeper basis for cooperation with Australia, including submarine interoperability, undersea warfare, workforce and technical expertise, infrastructure, sustainment, and potentially aspects of the industrial base. Analysts have already examined how Japan could fit into the wider AUKUS submarine ecosystem as Australia’s nuclear-submarine program develops.

A Japanese nuclear-powered submarine with a robust capacity to launch land attack cruise missiles would also be a powerful component in the country’s emerging “counterstrike” posture, which is increasingly centered on acquiring the ability to strike targets at longer ranges.

Japan has already begun deploying domestically developed long-range missile systems, including the Upgraded Type 12 surface-to-ship missile, while also acquiring the U.S.-made Tomahawk cruise missile.

An SSN would potentially add a highly survivable, mobile platform to this emerging strike architecture, allowing Japan to position long-range weapons farther from its home territory and complicating an adversary’s efforts to locate and neutralize them. That could be particularly valuable in a conflict in which Japanese air bases, missile batteries, and other fixed infrastructure were under attack.

The potential SSN requirement also fits with Japan’s expanding expeditionary ambitions. As the JMSDF converts its Izumo class helicopter destroyers to operate F-35B fighters, giving Japan a more credible carrier aviation capability, nuclear-powered attack submarines could provide a valuable escort for these increasingly important surface groups. Their speed, endurance, and ability to remain submerged for extended periods makes SSNs particularly well suited to accompanying carrier forces on longer-range deployments and supporting contingencies farther from Japanese waters.

Looking at the bigger picture, it is highly significant that nuclear propulsion was effectively excluded from Japan’s conventional defense debate for decades. More recently, however, Japanese defense officials and policymakers have begun examining whether future submarines will require a different propulsion system. The issue is now one that can be discussed openly at the ministerial level.

Nevertheless, pursuing a nuclear-powered submarine program would come with huge challenges.

Building and operating nuclear-powered submarines would require Japan to establish an entirely different industrial, regulatory, and training infrastructure. The vessels would also be considerably more expensive and complex to build and operate than Japan’s existing conventionally powered submarines. Tokyo would have to resolve questions involving nuclear regulation, reactor technology, maintenance facilities, crew training, and the handling of nuclear material.

There would also be a significant political dimension. Although naval nuclear propulsion is fundamentally different from possessing nuclear weapons, any move in that direction would inevitably receive scrutiny in a country whose postwar security policy has been shaped by its experience with nuclear weapons and its longstanding non-nuclear principles.

For those reasons, Koizumi’s statement should be viewed less as an announcement of a Japanese nuclear-submarine program than as evidence that the political barrier to discussing such a program is falling.

The next question is whether the Japanese government will move from keeping the option open to actually studying a nuclear-powered submarine design, propulsion technology, and acquisition pathway in detail.

If it does, the consequences could extend well beyond Japan’s submarine fleet. A Japanese nuclear-powered submarine capability would represent a major enhancement of Tokyo’s ability to operate across the Western Pacific and could alter the undersea balance between Japan, China, and the United States’ other regional allies. At the very least, the idea is one that is now part of wider discussions at the highest levels.

New Details About Secretive RQ-170 Sentinel Drone Squadron Shared With New Award

18 September 2026 at 16:16

An annual award has gone to one of the U.S. Air Force’s most secretive drone squadrons, offering a very rare window into its activities. The 30th Reconnaissance Squadron is one of two units known to operate the stealthy RQ-170 Sentinel, and it is unusual to hear anything about its operational exploits. Much about the RQ-170 itself remains highly classified 17 years after its existence was first officially acknowledged.

The General Atomics Remotely Piloted Aircraft (RPA) Squadron of the Year award for 2025 was presented to the 30th Reconnaissance Squadron at the Air & Space Forces Association’s (AFA) 2026 Air, Space & Cyber Conference on Tuesday, at which TWZ was in attendance. The AFA’s Mitchell Institute for Aerospace Studies works together with General Atomics’ Aeronautical Systems, Inc. division (GA-ASI) to recognize an Air Force drone unit in this way each year.

“The RPA Trophy is awarded annually at the USAF level for outstanding performance of active duty, Air Force Reserve, and Air National Guard … squadrons in achieving persistent attack and/or reconnaissance over the preceding calendar year,” the Mitchell Institute told TWZ in a statement. “Squadrons are judged on performance across their specified mission sets, exercise participation, and squadron and individual achievements.”

The institute sent an additional statement regarding this year’s particular award to the 30th Reconnaissance Squadron, which is as follows:

“Through relentless combat support, operational agility, and enterprise leadership, the 30th Reconnaissance Squadron – known as the Blackbirds – has set the standard for the remotely piloted aircraft community and strengthened the Joint Force’s intelligence advantage. In 2025, the 30th Reconnaissance Squadron conducted intrusive intelligence, surveillance, and reconnaissance missions across three areas of responsibility, filling critical intelligence gaps and disrupting enemy networks. In the face of urgent deployment requirements, the squadron demonstrated exceptional agility, rapidly pivoting resources to establish forward operating locations and execute critical missions under severely compressed timelines. The Blackbirds’ accomplishments paved the way for future remotely piloted aircraft capability, distinctly identifying them as the Air Force’s most outstanding RPA squadron.“

Larry Stutzriem, the AFA’s Executive Vice President, while presenting the award to representatives of the 30th Reconnaissance Squadron ahead of a panel at the Air, Space & Cyber Conference.

“In 2025, the 30th Reconnaissance Squadron conducted 87 ISR [intelligence, surveillance, and reconnaissance] missions across three different AORs [areas of responsibility], filled critical intelligence gaps, and disrupted enemy networks,” Stutzriem said. “On the unit mobility side, the Blackbirds executed 7.2 million dollars worth of airlift in six movements across four combatant commands, moving 250 tons of personnel, top secret material, and equipment to provide low-observable RPA support for a critical Secretary of War-directed mission.”

“With their deployments, the Blackbirds demonstrated exceptional agility under extremely compressed timelines,” he added.

Furthermore, during 2025, the squadron “also executed six large force exercises to develop tactics, techniques, and procedures; validated joint force tactical objectives in land and maritime environments; and provided combat-relevant training,” according to Stutzriem. “Instructors and evaluators graduated the largest ever combat mission-ready class, 30 percent ahead of schedule, and accelerated mission-ready status 33 percent, while increasing total unit aircrew by 26 percent.”

Though Stutzriem noted that the 30th Reconnaissance Squadron provided “low-observable RPA support,” no explicit mention was made of the RQ-170. Whether or not the squadron may now operate other kinds of low-observable (stealthy) drones is unknown. As mentioned, to date, the Air Force has only confirmed that Sentinels are assigned to two units, the other being the 44th Reconnaissance Squadron. Both the 30th and 44th are assigned to the 432nd Wing at Creech Air Force Base in Nevada. Between 20 and 30 RQ-170s, in total, are understood to be in the Air Force’s inventory.

What three specific AORs the 30th Reconnaissance Squadron operated in during 2025 is also not known.

However, at least one, and possibly two, RQ-170s took part in the mission to capture Venezuelan dictator Nicolas Maduro in January of this year, as you can read more about here. It’s very likely that the Sentinels were tracking Maduro ahead of the operation. In December 2025, Air Forces Southern (AFSOUTH) had also made a post on X that included a picture of an individual wearing a name patch with the silhouette of Sentinel and the sleeve insignia of the 432nd Wing, prompting questions about whether the drones were operating in the region. The post was subsequently deleted.

Further in the past, RQ-170s are also known to have been deployed to the Middle East, Central Asia, and the Pacific. The Sentinel first emerged publicly in Afghanistan in the late 2000s, prompting the U.S. military to confirm its existence in 2009. Sentinels are notably understood to have surveilled Al Qaeda founder Osama Bin Laden’s compound in Pakistan in the lead-up to the raid that led to his death in May 2011.

Later in 2011, one of the drones infamously went down in Iran while presumed to be on a mission to monitor aspects of that country’s nuclear program. With that in mind, it is possible, if not extremely probable, that RQ-170s likely played a role in relation to the Operation Midnight Hammer strikes on Iranian nuclear sites last year. Sentinels could have provided direct surveillance over the sites in question, as well as collecting post-mission bomb damage assessments and other intelligence. These are exactly the kinds of missions the drones were designed for and that operators have trained for.

A satellite image available through Apple Maps, seen below, also shows an RQ-170 at Naval Air Station Sigonella in Italy, likely in the 2023-2024 timeframe, based on the state of construction visible elsewhere at the base. It is not known how many Sentinels were deployed to Sigonella and for how long. The Apple Maps image does lend some credence to earlier reports that these drones may have flown missions in the Black Sea region, gathering intelligence on Russian forces on the heavily defended, occupied Crimean Peninsula, between 2022 and 2023.

Overall, the RQ-170 does still appear to be a go-to for performing penetrating tactical reconnaissance missions, especially when there is a need to provide persistent surveillance in denied areas, resulting in extremely important intelligence collection.

Again, it is important to reiterate here that we do not know if the 30th Reconnaissance Squadron operates any other stealthy drones beyond the RQ-170, or has in the past. A very stealthy high-altitude, long-endurance (HALE) surveillance and reconnaissance drone commonly and unofficially referred to as the RQ-180, or an evolution thereof, burst into the public eye in March after it was spotted landing in broad daylight at a base in Greece. Much about the drone, including what units are involved in its operation and where the home base of the fleet is, as well as the reasons for its deployment to the region, has yet to emerge. It does seem unlikely that the 30th would have taken on operation of the RQ-180, which is a larger strategic reconnaissance-focused platform compared to the smaller, tactically-minded, and less exquisite RQ-170. This is also just one example of what could still be lurking in the classified realm.

Whether or not the awarding of the 2025 RPA Squadron of the Year trophy to the 30th Reconnaissance Squadron might now point to a new willingness to talk about that unit’s activities and/or the RQ-170 remains to be seen. Regardless, the award and its description are yet more reminders of just how important the Sentinel remains nearly two decades after it first appeared.
