The U.S. Navy has taken delivery of the first C-130J-30 Hercules airframe destined to become an E-130J Phoenix II, the service’s next-generation aircraft for maintaining communications with its nuclear ballistic submarines. The aircraft will now undergo extensive mission-systems integration before it can begin testing for the Take Charge and Move Out (TACAMO) mission.

The @USNavy's future TACAMO aircraft is here.

Lockheed Martin handed over the newly built aircraft at its facility in Marietta, Georgia, on October 15. The delivery marks the start of the transition from the Navy’s aging E-6B Mercury fleet to the turboprop-powered E-130J, which is intended to provide a survivable communications link between national leadership and U.S. Navy nuclear ballistic missile submarines, including the ability to send them orders to launch strikes while they are submerged.

“Today’s delivery from the historic Marietta line represents far more than a new airframe; it marks the foundation of our future strategic deterrence posture,” Capt. Roger Davis, program manager for the Navy’s Airborne Strategic Command, Control, and Communications program office (PMA-271), said in a statement.

“Through our close partnership with Lockheed Martin and our industry team, we are ensuring our nation maintains an unshakeable communications lifeline to our ballistic missile submarine fleet.”

The aircraft is the first of three C-130J-30s initially procured by the Navy in September 2024. It will be transferred to Northrop Grumman, the E-130J program’s prime contractor and mission-systems integrator, for conversion. Collins Aerospace is providing the very low frequency (VLF) communications system, a key component of the TACAMO mission.

TACAMO aircraft provide a means for the president, secretary of defense, and U.S. Strategic Command to communicate with nuclear forces, including submarines submerged at sea. The mission is designed to preserve the ability to transmit emergency action messages even if conventional communications infrastructure is disrupted or destroyed.

The E-6B accomplishes this in part through a long, trailing wire antenna that enables VLF transmissions to submerged submarines. The E-130J will receive a comparable system as part of its conversion.

Hardening against the effects of electromagnetic pulse (EMP), which occurs during the detonation of nuclear warheads, is another key requirement for these planes.

The Navy plans to acquire 31 E-130Js, nearly doubling the 16 E-6Bs currently in service. That total includes six developmental aircraft and 25 production examples, although it remains unclear how many of the developmental aircraft will ultimately be available for operational use.

The larger planned fleet should provide additional aircraft to support training, maintenance, and operational demands. However, the transition also brings technical challenges. The Government Accountability Office (GAO) has previously warned that integrating the specialized mission equipment into the smaller C-130J-30 airframe could affect operational availability and create additional engineering and manufacturing difficulties.

In the past, TWZ has discussed the potential operational readiness and other trade-offs that could come from selecting a C-130-based platform to replace the E-6B in the TACAMO role. As we wrote previously:

“It’s certainly worth pointing out that the E-6Bs, conversions of what were some of the last and most modern 707 airliners built, were larger and higher performance platforms than the EC-130Qs. The C-130J-30 is certainly a more capable aircraft than the C-130H on which the EC-130Q was based, but it won’t have the base speed and altitude capabilities of an airliner-sized multi-engine jet. Compared to the Mercuries, any TACAMO-configured C-130J-30 would not be able to get on station as quickly, or fly as high, limiting its ability to get above bad weather or establish a better line of sight for its communications systems.”

“At the same time, as the Navy itself has noted, the C-130J-30 platform does immediately open up the ability to use a larger number of air bases, airports, and airfields, including austere ones that the E-6B cannot operate from. This could be very useful in a contingency scenario where an opponent may have destroyed or otherwise rendered unusable many well-established bases, as well as larger secondary dispersal sites, which include large commercial airports. Being able to fly from smaller, tertiary locations could help to ensure that the TACAMO mission continues without significant disruption under such circumstances. This is also true during peacetime, as targeting the TACAMOs on the ground would be much harder if they could easily operate from and sit alert at a much larger number of airports.”

“A C-130J-30 configured for the TACAMO mission would certainly have a mid-air refueling capability, and the Hercules is already a platform that has demonstrated the ability to loiter over particular areas for long periods of time. Unlike the Boeing 707, the C-130J is still in production, as well, meaning that TACAMO aircraft based on this plane would be inherently easier to maintain and support logistically, and may also be easier to convert to this specialized configuration to begin with. As time goes on, the J looks set to increasingly become the default base C-130 model across the U.S. military, as well. Compared to the long out-of-production 707-based E-6, support for the C-130J is already distributed across the U.S. and beyond. Training C-130J crews is even an easier proposition.”

The E-130J also represents a return to the Hercules family for the Navy’s TACAMO mission. The EC-130Q performed the role from 1963 to 1993, before the E-6A Mercury took over. The E-6B subsequently added an airborne command post mission known as Looking Glass, supporting U.S. strategic forces beyond the submarine communications role.

The Navy’s current plan is for the E-130J to assume the TACAMO mission, while the Air Force pursues a separate effort to replace the Looking Glass airborne command post capability.

Following its delivery, the first E-130J airframe will enter mission-systems modification, ground testing, and developmental flight testing. The aircraft is not yet an operational TACAMO platform, and further integration and testing will be required before the Navy can begin fielding the new fleet.

The transition is intended to preserve one of the most critical links in the U.S. nuclear command, control, and communications architecture as the E-6B fleet becomes increasingly difficult to sustain.

America’s nuclear weapons deterrent and how it is controlled is increasingly critical in the face of the rapidly-expanding arsenals across multiple adversaries. A new fleet of E-4C nuclear-hardened survivable airborne operations center aircraft is now in development, as is the U.S. Navy E-130J, which will provide next-generation communications with nuclear ballistic missile submarines deep beneath the waves. Focus is also turning to a mission that’s dedicated to emergency communications with the U.S. nuclear forces in times of crisis, a role known as Operation Looking Glass, which is also poised for updating under a program dubbed Looking Glass-Next.

The comprehensive modernization of America’s nuclear strike muscle involves three major elements – new B-21 Raider stealth bombers, the LGM-35A Sentinel intercontinental ballistic missile (ICBM) program to replace Minuteman IIIs, and new Columbia-class nuclear ballistic missile submarines. A fourth facet that ties all these new elements, as well as existing ones, together is the next generation nuclear command, control, and communications (NC3) architecture. It securely connects nuclear weapons systems to decision-makers. Without it, America’s nuclear deterrent isn’t a deterrent at all.

America’s nuclear modernization is set against a backdrop of rapidly-developing nuclear strength across adversaries and pacing threats, which could threaten not only U.S. fighting forces, but also the existing aging NC3 infrastructure. This could impede the collective responsiveness and effectiveness of the American nuclear enterprise. For example, a coordinated attack on NC3 could degrade the National Command Authority chain, which could prevent communications that are necessary to conduct a retaliatory strike.

If fixed underground command posts are targeted and rendered inoperable, the current strategy would involve turning to a set of highly-survivable air assets that are designed to be on hand to execute emergency war orders. This includes the U.S. Air Force’s E-4B National Airborne Operations Center (NAOC) “Nightwatch” aircraft, and the E-6B Mercury that is operated by the U.S. Navy.

A major recapitalization effort is already underway for the NAOC E-4Bs, which are being superseded under the E-4C Survivable Airborne Operations Center (SAOC) contract. It is being led by defense contractor SNC. The new SAOC aircraft are based on the far more modern 747-8i, and are planned to have a much broader mission set than the four E-4B Nightwatch types they are set to replace, as you can read more about here.

The Navy’s E-6B Take Charge and Move Out (TACAMO) aircraft have a primary role of strategic connectivity with the ballistic missile submarine fleet. These converted 707s also execute another mission known as the Airborne National Command Post (ABNCP), more recently renamed “Looking Glass.” For this they are manned by U.S. Air Force missileers and U.S. Strategic Command (USSTRATCOM) battle managers who are responsible for running the airborne nuclear NC3 systems.

The joint service team on Looking Glass mirrors some operations performed by USSTRATCOM’s underground command posts, and a small portion of what the NAOC executes. The Looking Glass mission is really focused on performing an airborne backup mission solely for USSTRATCOM to ensure another means of communicating with fielded nuclear bombers, their assigned tankers, ICBMs and deployed nuclear submarines. It is best known for its ability to supply airborne communications connectivity to the USAF’s ICBM force on the ground and can command remote launches of those weapons if necessary.

Additional NC3-related modernization is coming on the heels of SAOC, with the new E-130J set to assume the Navy’s TACAMO role from the ageing E-6Bs, assuming strategic connectivity for nuclear ballistic submarines. It means that at some point roughly two-thirds of the E-6 current mission will go to the new E-130J aircraft – raising the question of what will fulfill the critical Looking Glass mission.

Since the E-130J is not planned to take on the Looking Glass role, the USAF is in the early stages of what’s dubbed Looking Glass-Next (LG-N), which presents the future pathway for USSTRATCOM’s mobile contingency operations. This could take on a number of forms, including NC3 communications functions being increasingly moved to space-based assets and more distributed operations across the ground, although an air platform is still likely to form a major part of the overall capability.

The need to modernize America’s NC3

Brian Golden is a retired USAF colonel who intimately understands nuclear command and control (NC2) and the associated NC3 equipment and processes from both a service and industry perspective. As a subject matter expert for SNC, he draws on his extensive experience as a former E-4B NAOC commander and he commanded much of the USAF’s multi-domain NC3 systems, including the Airborne Launch Control System onboard the current E-6B Looking Glass. He is also extremely familiar with all the nation’s continuity of government and continuity of operations missions for both Congressional and executive branches of the U.S. government.

“Everyone referred to the nuclear triad as the platforms that were controlled through the NC3 architecture,” Golden told TWZ during a detailed discussion. “Those platforms received their messages and executed their missions. But this isn’t just about that platform triad. The U.S. nuclear enterprise has four primary pillars, and nuclear command, control, and communications is a critical part of it. Without a robust NC3 system, it’s like having a brand new Bugatti Veyron but without the keys! It looks awesome on the driveway, but you can’t drive it.”

Golden explains that the current NC3 enterprise consists of a series of exquisite systems that are extremely reliable, but that are in need of modernization to stay ahead of the steepening threat curve, and stay in front of supply chain constraints. “What we have currently is very reliable, robust, and very survivable, but it can be difficult to maintain some of our legacy systems. Additionally, as threats evolve we must ensure our communications pathways also evolve. 

“Our nation’s industrial base engineers figured out extremely robust methods of nuclear communications when these systems were fielded. Looking at the overall command and control [NC2], and then the NC3 communications pathways, any new systems that we introduce must be sustainable, scalable and modular.”

The U.S. nuclear enterprise is facing greater threats than ever with adversaries challenging U.S. nuclear infrastructure in multiple domains: space, cyber, ground, air. Because of this, NC3 demands a continuous process of improvement.

Going forward, the NC3 enterprise will likely need to integrate upgraded proven legacy systems with all-new technology. “Sometimes the physics of radio waves may dictate the need for a legacy approach with upgraded systems, such as communicating with a submarine that’s very deep in the ocean.”

Golden’s view is that NC3 requires a layered, open architecture approach as modernization is evaluated. “Applying those same physics and then adding new layers such as artificial intelligence may determine a better way of doing things.”

Upgrading to SAOC

Golden points to the SNC-led E-4C SAOC program as a clear example of critical NC3 modernization, while emphasizing that the NC2 mission is far from being the primary role of the E-4B and its forthcoming successor. “Nuclear command and control is only a fraction of what the current NAOC does and what the future SAOC will do for our nation and our allies and partners.”

The E-4B initially featured just a handful of communications systems, which have grown over time, leading to what Golden calls the “King Kong” of communication capabilities today. The E-4 is not a battlefield communications platform, its mantra is all about supporting Presidential-level requirements across the board. It does possess an extensive NC3 suite, but it also serves the White House Communications Agency (WHCA) and the Department of Homeland Security, through the Federal Emergency Management Agency (FEMA), in many other crisis roles. Another mission the E-4B fleet performs is to safely transport the Secretary of War on trips within the United States and abroad.

The E-4B NAOC and Looking Glass are two complementary tiers of the same survivable architecture. The NAOC (and future SAOC) is designed to anchor national-level decision-making and government continuity from the very top, while Looking Glass provides USSTRATCOM with the dedicated airborne command and battle-management capacity required to direct forces. Both roles are critical and non-negotiable.

“The new E-4C SAOC, like the E-4B before it, will deliver an expansive communications suite and increased capacity supported by a larger fleet,” Golden explains. “SAOC is built to ensure the President and national leadership can direct the entire country through any crisis. Looking Glass supports an equally vital and highly specialized mission. It is dedicated to USSTRATCOM’s operational needs, connecting directly to bombers, ICBMs and submarines. Attempting to merge these unique missions on a single airframe would compromise the unique, essential role that each was created to perform.”

Looking Glass-Next

The Looking Glass role and the platform that fulfills it is not classified as a national-level mission. As Golden alluded to earlier, it’s not assigned to the Chairman of the Joint Chiefs or to the Secretary of War. It’s exclusively assigned to USSTRATCOM; however, without the Looking Glass mission being upgraded soon, America has a gaping hole in its nuclear architecture.

The commander of USSTRATCOM is the customer and ultimately the decision-maker when it comes to Looking Glass-Next, and the USAF has been tasked by the Secretary of War to develop and field it. SNC is looking at several options for the requirement, with some sort of air platform at its core, which Golden refers to as an “E-6C.” He endorses that the current E-6B is one of the “cogs in the wheel that has to be replaced,” but adds that this doesn’t mean the next-generation Looking Glass is just an aircraft.

“At SNC, we have significant expertise and experience with mission system integration,” says Golden, adding that SNC is evaluating what he calls “aggressively creative options,” for the modernization requirement. He further noted that the modern threat is driving a requirement for Looking Glass-Next to be very difficult to target and must be dispersed.

“Having an aircraft as the only option for this USSTRATCOM mission is a legacy mindset,” Golden states. “We have advanced multi-domain capabilities, including numerous space capabilities available through the Sierra Space Corporation. Future mission resilience requires a creative and integrated approach.”

“We believe a creative approach to provide NC3 options will ensure a robust, reliable, survivable and cost-effective solution.”

Golden endorses this approach to creativity and development and indicated that SNC will continue to inform and respond to the ongoing Looking Glass-Next requests for information that may result in a future program.

“SNC has leaned heavily into the nuclear command, control, and communications architecture and it’s a natural fit for us, building on our work with the Department of War and our subcontractors on the E-4C SAOC. Our Looking Glass-Next responses and inputs will leverage relevant work and experience gained from SAOC, but we are also focused on being creative. We’re small enough to be agile, but big enough to deliver. That’s why we think we’re very well positioned in the NC3 space.”

The majority of SNC’s work on the E-4C SAOC is being completed at the NC3 Center of Excellence, housed in the Aviation Innovation and Technology Center (AITC) in Dayton, Ohio. 

Golden believes the timing couldn’t be better to deliver bold and creative NC3 solutions. “The USAF is already asking the right questions, and industry is really able to innovate, which will result in a transformational era for nuclear command, control and communications.”
