The head of the U.S. Army Space and Missile Defense Command (SMDC) was initially skeptical about the utility of high-altitude balloons, but now sees them as a “game-changing” capability. Lt. Gen. John Rafferty’s comments follow a separate disclosure that the Army axed plans for a balloon swarm test in the Pacific last year and instead sent those systems to support real operations in the Middle East. TWZ has been closely tracking the expanding use of high-altitude balloons and other lighter-than-air systems globally for intelligence gathering, as platforms for launching drones, and in support of other missions, for years now.

Lt. Gen. Rafferty was asked about high-altitude balloons during a media roundtable today, at which TWZ was in attendance, on the sidelines of the Association of the U.S. Army’s (AUSA) main annual convention. Army Col. Joseph Mroszczyk, head of SMDC’s Transformation Integration Directorate for Space Superiority (TID-Space Superiority), also discussed the service’s use of balloons during the roundtable. Breaking Defense first reported on the shift of balloon-based capabilities from the Pacific to the Middle East on Monday.

“I’ll just give a little personal history on high-altitude balloons. I started in the Army Futures Command in the Long Range Fires-Cross Functional Team. There was this talk of high-altitude balloons. I think it was the ISR [intelligence, surveillance, and reconnaissance] task force was talking about it,” Rafferty said. “It just sounded crazy to me that we were considering this.”

“Then, a few years later, when the Sergeant Major [SMDC Command Sgt. Maj. Rickey Jackson] and I were together in the multi-domain community in Europe, I went with the 2nd MDTF [Multi-Domain Task Force] to Morocco for training and experimentation,” he continued. “[I] saw the high-altitude balloons in action, and I was immediately convinced after I understood better how they worked and how their ability to station-keep, and their ability to sense and even deliver effects from high altitude. It was game-changing for me.”

Broadly speaking, the main benefit that modern high-altitude balloons offer is their ability to be deployed persistently for days, weeks, or even months at a time. Designs available on the market today can hold their position, in spite of prevailing winds, and moderate their altitudes to keep on station, after precisely navigating to an assigned operating area.

On top of their persistence, the altitudes at which these balloons operate provide excellent fields of view for radars, cameras, and other sensors in all directions and across very broad areas. From a perch of 60,000 feet or more, they also offer a way to peer into certain denied areas while still soaring in international airspace and keeping further away from potential threats.

The video below from high-altitude balloon maker Aerostar offers a good general overview of the kind of capabilities on the market today.

As Lt. Gen. Rafferty noted today, ISR is not the only use case for high-altitude balloons, either. They can serve as communications relay nodes, as well as launch platforms for swarms of drones and other expendable payloads. These are all capabilities the Army has explicitly talked about as part of broader plans for balloons in the past. Other countries, especially China, are already actively employing high-altitude balloons for ISR and other missions, as we will come back to later on.

“In my former role as an MDTF commander, we experimented a lot in the Pacific with those [balloon-based] capabilities. We have leveraged different size platforms,” Col. Mroszczyk added today. “In this [TID-Space Superiority] role, as a proponent, what I’m pushing for is a family of stratospheric systems that really covers smaller size all the way up to larger size types of platforms in terms of balloons.”

“What that enables us to provide is space-like capabilities, really exploiting a transition point between what is normally considered the aerial layer and the space domain,” he continued. “Really, where you go from about 60,000 feet to 100,000 feet is what we focus on in the stratosphere. That operational space allows some persistence and broad coverage in an area where you can deliver space-like capabilities in terms of payloads, but then also take advantage of the deep access that you get from a stratospheric balloon.”

“So, being able to go, take advantage of winds that are pushing you where you want to go already to be able to get either launched effects or other types of payloads for sensing and communications and extension of your launched effects portfolio,” he added. “That is a way that we can help exploit the stratosphere, and we’re looking to do that throughout multiple experiments over the course of the coming year.”

“Launched effects,” is a catch-all term the U.S. military now routinely uses to talk collectively about uncrewed aerial systems designed to be launched from other platforms in the air, on the ground, and/or at sea. This encompasses drones configured for a wide variety of missions, including surveillance and reconnaissance, electronic warfare, signal relay, and even kinetic attack.

Col. Mroszczyk talked about plans to further demonstrate how high-altitude balloons will be commanded and controlled, as well as networked together with other Army capabilities, when asked to elaborate on what the forthcoming experimentation would entail.

As mentioned, the Army had also planned to demonstrate the ability of balloons to operate in swarms with a high degree of autonomy in the Pacific region last year before those assets were redirected to the Middle East. When exactly that deployment occurred and how long it lasted are unclear.

“We were asked to pivot and do some experimentation in combination with operations, and we pivoted and supported operations in CENTCOM [U.S. Central Command],” Andrew Evans, Director of Strategy and Transformation with the Office of the Deputy Chief of Staff of the Army, or G-2, told Breaking Defense, per the story that outlet published on Monday.

“They were effective for the mission that they were assigned,” he also said, but declined to elaborate further, according to Breaking Defense. “Balloons can be a little finicky in terms of temperature, and you have to contend with environmental characteristics.”

“We had a lot of help from vendors in this space, but as you think about employing your systems and going from something like a Pacific [theater] to something like a CENTCOM [theater], you learn where those friction points might exist between what the military might need to inherently own, and … what a vendor could help provide in terms of the service,” Evans added. Furthermore, “balloons can be a little finicky in terms of temperature, and you have to contend with environmental characteristics.”

The remarks today from Lt. Gen. Rafferty and Col. Mroszczyk underscore the Army’s commitment to fielding new high-altitude balloon-based capabilities and the immense benefits the service sees in them. However, the continued emphasis on testing and experimentation highlights a discrepancy with the state of the service’s current efforts, and even more so in light of global trends.

The Army has been openly talking about balloons as part of its vision for a new multi-layered persistent sensor architecture, and how they could also be used to launch drones and other ‘effects,’ for at least six years now. In that same time, China has very actively shown off its ability to gather intelligence and conduct other missions using balloons and other lighter-than-air craft on a broad operational level across the Pacific. TWZ had been reporting on this reality for years before it was thrust fully into the public consciousness after a Chinese spy balloon passed over parts of the United States and Canada back in 2023.

Other countries, including U.S. allies and partners, are increasingly fielding balloon-based and other lighter-than-air systems, too. Forces in Ukraine have notably been using balloons to conduct kinetic attacks and launch drones in the course of the ongoing conflict with Russia. On the other side of that conflict, Russian forces have used balloons as decoys to confuse and misdirect air defenses.

The Middle East deployment does show new efforts on the Army’s part to operationalize high-altitude balloons on a more widespread basis, but also that it is still relying on largely experimental capabilities to do so. Earlier this year, the service called attention to the establishment of a new schoolhouse for high-altitude balloon training to help further lay this groundwork, further underscoring how all of this is still very much in its infancy.

The remarks today from Lt. Gen. John Rafferty, especially, show there is substantial support within the Army for pushing ahead with high-altitude balloon programs. At the same time, there is clearly much work to be done if they are to have a truly game-changing impact, while the gap with China and others only continues to grow.

The post High Altitude Balloons Are A “Game-Changing” Capability: Army Space Command Boss appeared first on TWZ.

Sikorsky is aiming to start offering a new modular and readily swappable nose for the venerable H-60 family of helicopters within the next year or so. The noses will be made available on new-production H-60s, as well as be retrofittable to helicopters in service now. The ‘nose jobs’ will help operators relatively quickly reconfigure their H-60s for very different missions, from cargo-carrying to serving as gunships, as required. It also opens new avenues to integrating autonomous capabilities and other advanced functionality.

Our Howard Altman had a chance to speak with representatives from Sikorsky, now a subsidiary of Lockheed Martin, about the plans for the new nose for the H-60-series at the Association of the U.S. Army’s (AUSA) main annual convention today. This is part of a larger vision for keeping the design operationally relevant into the 2070s, which also includes uprated engines and increased total payload capacity. You can read more about the overall Black Hawk 2070 strategy here.

Of the different elements of Black Hawk 2070, “the nose is a good one, and it’s one that’s on a pretty accelerated timeline. Within the next, I would say, year or so, the nose will be available to be retrofitted or to be coming off the line,” Jason Wrigley, Sikorsky’s director of business development for Black Hawk, said. “We’ve gone through a design cycle with it.”

As it stands now, the new nose structure will offer roughly double the physical space of the standard nose on current-generation H-60s today.

“We’ve done the design. We then 3D-printed the noses, and we did that so that we can physically interact with it, because the whole point of this is for maintainability and access to be able to integrate these different sensors and comms gear,” he continued. “We’ve gotten some feedback from the engineers, from operators, from maintainers, and that goes back into the next cycle of the design.”

Exploring ways to optimize accessibility to areas of the new nose was a major focus of this ‘test print,’ according to Wrigley. Sikorsky has a scale model on the show floor at AUSA this week that highlights how the current design opens from the top, as seen below. Ensuring that it will be possible to keep any systems inside sufficiently cooled has also been an important design consideration already.

Overall, “we just are kind of confirming, can we reach everywhere we need to? What are the different configurations?” he added. There’s been “a lot of work with the [U.S.] Army around what do you envision potentially could go in here?”

“This is one of those cases also where our whole engineering team gets more comfortable. It’s not something where the Army came to us and said, ‘this is exactly what I want. Here’s my spec,'” he also noted. “It was more, ‘here’s what I want to achieve. Here’s what I want to be able to do.’ And so we went off and designed that.”

“I like to highlight this, because it’s part of the way we’re also changing the way we design and deliver the Black Hawk,” Wrigley added as an aside. “So we’re very much in a model-based environment.”

While Wrigley mentioned sensors and communications equipment as possible payloads to fit into that extra space initially when talking with us today, he made clear later on that these are just some of the potential options.

“It’s using the old term, but it’s open architecture, and so the whole point is whatever the mission requires” can go into these new extended noses, he explained. “There’s always a demand for real estate up front.”

It’s very true that more specialized variants of the H-60, such as the MH-60s operated by the U.S. Army’s elite 160th Special Operations Aviation Regiment, often have modified noses loaded with radars, other sensors, and additional systems. The new HH-60W Jolly Green II rescue helicopters for the U.S. Air Force are another prime example of this, and there are many more.

“There’s a big focus on open architecture and that ability to quickly plug-and-play,” Wrigley also told TWZ earlier this month in the context of the larger Black Hawk 2070 plan. “The new modular nose will change the look of the Black Hawk up front to provide even more space for equipment that will work directly with the new digital architecture.”

In terms of swapping out modular noses on individual helicopters, Wrigley said that it is still too early in the design process to know exactly how that would be done and how long it might take to do so in practice.

“Part of the design process is to also write up the documentation for the retrofit, but we don’t see this one as very invasive,” he explained.

It is not hard to imagine use cases for long-nosed H-60s, especially ones that can then be reconfigured between missions, and not just for the U.S. Army. As Wrigley already underscored, there is long-standing demand for H-60s with longer and larger noses to accommodate additional mission systems. Modular noses, in general, have been becoming more and more common in aviation design for some time now.

The ability to readily swap modular noses could also allow operators of even relatively small H-60 fleets to gain a valuable new degree of multi-mission capability. As one example, cargo-carrying helicopters could be converted into gunships, and back again, as required, using a small common pool of noses with the requisite sensors, laser designators, and other equipment. All of this could offer cost benefits when it comes to sustainment and logistics, as well as added operational flexibility.

The long-nosed Black Hawk model on display at AUSA is notably configured as a gunship. Sikorsky has also talked previously about leveraging the new nose to reconfigure H-60s for search and rescue, airborne drone control, and other missions.

Just being able to install a radar for one series of missions, and then quickly switch over to an electro-optical wide-area surveillance system or another kind of sensor for the next run of sorties, would bring new adaptability to the already very flexible Black Hawk. Defensive systems could also be readily swapped from aircraft to aircraft, as well as more quickly upgraded, as needed.

The modular nose also opens the door to a new way to integrate advanced capabilities, including autonomy packages, which Wrigley said is also driving demand for more space at the front end of the helicopter. Sikorsky has been developing various tiers of autonomous capabilities for the H-60 family for years now, including artificial intelligence-driven ‘copilots’ designed just to help reduce the workload of human crew members and increase safety margins. Autonomous flight capabilities require additional sensors, such as LIDAR and cameras, to help with navigation and to provide additional situational awareness. At least some of those components could be hosted within new modular noses.

At the same time, integrating higher degrees of autonomy could require more substantial modification. Sikorsky is now developing a fully uncrewed version of the H-60, and has been doing so with an eye toward converting older Black Hawks to this configuration as they are retired from service, as you can read more about here.

In line with the Black Hawk 2070 vision, the modular noses could be part of a broader equation for modernizing existing H-60 fleets, as well.

“In our conversations with the Army, I think they’ve been using a phrase that they call targeted modernization,” Wrigley told us, speaking more generally. “There’s a daunting task that says there’s 1,000-1,500 Black Hawks in inventory. If you literally tried to upgrade every one of them, it’s a very expensive proposition, and it probably takes a long time.”

“I don’t think that’s the way they’re thinking about it. I think they’re thinking about it more on a battalion basis or a unit basis,” he continued. “Like, what’s the mission, and maybe certain Black Hawks get upgraded with autonomy, and other Black Hawks get upgraded with sort of the expanded launched effects capability, the engine, the structural upgrades, the [stub] wings, stuff like that.”

“Maybe some of them become ‘Superhawks’ or whatever, [and] get the whole package,” he added.

There is certainly still work to be done on the development of the new modular nose and then actually integrating it onto the H-60 platform. At the same time, Sikorsky clearly already sees demand for this new feature, which could lead to a breadth of new opportunities for new and old helicopters in the H-60 line.

Feedback from the U.S. Army has led to an improved A1 version of the service’s still very new 6.8x51mm M250 light machine gun. Manufacturer Sig Sauer has shortened and lightened the barrel, reduced the overall weight, changed the buttstock, and made various other improvements to improve reliability and ease of use. The evolution of the M250 mirrors the transformation of Sig’s M7 rifle for the U.S. Army into the M8 carbine, where weight and bulk were major points of criticism of the original design.

Jason St. John, senior director of strategic products for the Defense Strategies Group at Sig Sauer, talked about the new M250A1 with our Howard Altman at the Association of the U.S. Army’s (AUSA) main annual convention today. The U.S. Army has already been acquiring and fielding baseline M250s as part of its Next Generation Squad Weapons (NGSW) program. The NGSW family also includes the M7 rifle and now the M8 carbine from Sig, both also chambered to fire the 6.8x51mm round. The Army chose Sig as the winner of the NGSW competition in 2022. The service is still in the early stages of fielding the NGSW family as replacements for a substantial portion of its existing 5.56x45mm M4A1 carbines and M249 Squad Automatic Weapons (SAW).

“We continuously and constantly evaluate and evolve our designs, and we discover things,” St. John told us. “Parts that might be able to be manufactured a little bit easier with a little bit of a design change. They might be more reliable, more durable than you currently have. You might look at the system and say, hey, we have an ability to make these recommendations because we see this from other customers across the board. We hear it from our inputs of soldiers that are in our ranks, and you know maybe old relationships out in the field.”

“The [NGSW] program office represents the entire formation, so they get feedback in the totality of every single unit that has them [M250s and other guns in the NGSW family] in their hands,” he continued. If “a systemic issue or something that needs to be addressed, then they run the soldier touchpoint events, which we’re fortunate enough to be a part of. And then we get unfiltered feedback from soldiers that day in the field while they’re encountering something that they have a concern about.”

As noted at the start, the most immediate standout feature on the M250A1 being shown at AUSA this week is the new 13-inch barrel. M250s entering Army service now have roughly 16-inch-long barrels. The Army’s official fact sheet says the machine gun was originally expected to come with a 17.5-inch barrel.

“We shortened the barrel to 13 inches, but the Army’s also buying the 16-inch barrel,” St. John explained. “So in some ways, you could consider it mission-configurable, whether they want to utilize a 13-inch barrel or a 16-inch barrel, to what they’re doing.”

“You’re going to maintain the same basic ballistics that you had with the M7 [rifle’s] 13-inch barrel, and then you’re going to have more maneuverability because you’re going to have a shorter weapon system,” he added. “You add the 16-inch barrel, and you get that lethality requirement with the length of barrel that they originally required. So you have some flexibility there.”

“You shorten the barrel, you’re going to lose velocity,” St. John did acknowledge. “We did not change the ammo. The Army had determined with the barrel change that they were meeting their ballistic and lethality goals with that length of barrel.”

With the current 6.8x51mm ammunition, “we’re operating in the mid-70s [sic; 70,000 pounds per square inch] as far as pressure, and the case has 125K psi potential,” he also noted. “If you wanted to shorten the barrel and you did have some lethality concerns or wanted more performance, all you need to simply do is just increase the little bit more pressure in the cartridge case, and you overcome that shortness.”

“We didn’t do that. The Army said it wasn’t necessary, but you know, as the battlefield evolves and defensive postures change, if that becomes necessary, one of the great things about the NGSW program is the ability for the weapon systems and the ammunition to grow in their performance capacity,” he continued.

In the case of the 13-inch barrel, “we tapered the barrel down a little bit to add a little bit of weight savings,” he noted.

TWZ has reached out to Sig about getting more complete specifications for the M250A1, including overall length and total weight with different barrel options. The baseline version weighs some 13 pounds, empty, and without optics and other accessories, according to the Army’s fact sheet. As already mentioned, the M7 rifle also got progressively shorter and lighter before giving way fully to the M8 carbine, in part through reprofiling of the barrel. The empty weight of the M8 with its 10-inch barrel is close to one pound less than that of the 13-inch barreled M7.

Different barrels can be readily swapped out on the M250A1, as well as the baseline M250. However, the new variant features significant changes to the quick-change barrel arrangement on the gun and associated elements of the design.

“It was interchangeable before, but it didn’t have a quick-change barrel handle. It wasn’t meant to be changed, and therefore it didn’t need the insulation of [sic; for] a hot barrel like you get with a barrel with a quick-change barrel handle,” according to St. John. “I think initially with the [M]250 program, it wasn’t necessary, and potentially might not have been desired initially. And why put that weight burden on there if we weren’t going to utilize it, right?”

St. John did not elaborate further on why these features were initially deemed unnecessary.

“When you look at the top cover of the forearm, that used to be loose, and now it’s captured, meaning that when you change the barrel, it actually came off completely in your hand,” he also noted. “We utilized a similar design to our .338 MMG [Medium Machine Gun], and then we make it captured now, so you’re not going to lose it.”

“We added a funnel to guide your gas piston in, so that when you’re doing barrel change operations, you don’t have to be precisely lined up,” he added. Now, “you have something that’s going to guide it in a stressful environment, to get that into position to do your barrel change.”

The M250A1 features a host of other changes that are unrelated to the barrel.

Sig also “improved our gas system a little bit, just to make it more reliable and durable,” to include modifications to keep it better “insulated from carbon and things like that.”

“We opened up the trigger guard to incorporate the Arctic fight, the Arctic glove, more so than just the operational normal tactical gloves,” according to St. John. “We opened it up a little bit more to accomplish that.”

The Arctic is an ever-more strategic region where the U.S. faces growing geopolitical competition, especially from Russia and now China. Army officials also regularly point out that the harsh environment presents challenges when using standard equipment designed around use in more temperate locales.

“We improved the buttstock, and we improved the interface … to the receiver,” St. John explained. “We’ve made the interface between that more robust because through IMTing, and over time, and the buttstock getting slammed on the ground, and just normal military training and operations, we noticed that we had a tendency for some of them to loosen up and have some play in them.”

“The entire buttstock is a different buttstock than they had,” he added. “They [Army soldiers] preferred that buttstock over the buttstock that we had on it. So we just put soldiers’ preference on there. … It’s just a commercially available [design from] Magpul that they thought was better than the other Magpul that day one we were using.”

Changes were made to points where the M250 is designed to be attached to tripods on the ground or pintle mounts on vehicles.

“We put cross-bolts through the receiver to provide more durability,” he explained. “Initially, it was like an M-LOK type of lockup, and you can just think of a steel nut on an aluminum receiver being vibrated over a life cycle of the weapon system, it has some unfortunate wear characteristics. So, putting these cross pins redirects that force, and the way we lock it down with a saddle screw prevents that from happening and provides long-term durability to the receiver in the pintle and T&E [traverse and elevation] tripod-mounted configuration.”

The continued evolution of the M250 is not new. Sig talked to TWZ at AUSA last year about changes, including to the bipod and top cover, that were already making their way into the design.

The Army has yet to formally adopt the M250A1 configuration, and further changes could be made before service moves to officially acquire an improved version of the gun.

“This is likely to be the accepted configuration. We anticipate that acceptance,” Sig’s St. John told us. “We just finalized the acceptance on the M8, and they’re moving into the acceptance of the [M]250s. We anticipate right now, with the feedback that we’re getting from the program office, that the majority, if not all, of these changes are likely to be accepted.”

It’s important to reiterate that changes to the M7 rifle, and then the Army’s decision to transition fully to the further evolved M8 carbine, followed significant criticism of the core design of those guns and their ammunition, as well as the underlying doctrine. Sig has repeatedly pushed back on those critiques, and the Army continues to push ahead with the entire NGSW program.

Despite the steadily shortening barrels on guns in the NGSW family, the Army’s position remains that the weapons chambered for the new 6.8x51mm round offer essential additional accuracy, range, and terminal effectiveness over existing 5.56x45mm types. The genesis of the NGSW program had been heavily informed by the war in Afghanistan, where there were regular reports of U.S. ground units being outranged by their opponents. Adversary body developments were also a factor.

It is also important to point out that teething troubles are not at all uncommon in major weapon system programs, including when it comes to small arms. Sig has drawn attention to the less than positive reception that the AR-15/M16 family initially received in the mid-1960s, which led to a host of changes to that design. Rifles and carbines in that pattern are now in widespread service across the U.S. military and with dozens of armed forces and security services globally.

Regardless, even with the Army still very early on in the process of fielding the entire NGSW family of guns, the M250 light machine gun’s design is now evolving significantly.
