Latest updates[?]: Rockwell Collins won a $16.9 million order, which upgrades the E-6B Mercury mission computer from a 32-BIT to a 64-BIT Linux-based operating system, resulting in an increase to capability and reduced threat vulnerabilities. The principle mission of the E-6 Mercury is to connect the national command authority with the US Navy’s nuclear missile force carried aboard at-sea ballistic missile submarines. The E-6 is a militarized version of the commercial 707 civilian airliner and carries a very low frequency communication system with dual trailing wire antennas. Work will take place in Richardson, Texas and is expected to be finished in March 2023.
E-6B TACAMO
The USA’s E-6 Mercury (aka. TACAMO, as in TAke Charge And Move Out) “survivable airborne communication system” airplanes support their Navy’s SSBN ballistic missile submarine force and overall strategic forces. With the advent of the new “Tactical Trident” converted Ohio Class special operations subs, their unique capabilities become even more useful. The E-6B version also has a secondary role as a “Looking Glass” Airborne National Command Post, and in recent years they have seen use as communications relay stations over the front lines of combat.
Delivery of the first production E-6 aircraft took place in August 1989, with delivery of the 16th and final airplane coming in May 1992. This is DID’s FOCUS Article concerning the E-6 system, which includes details concerning the capabilities and associated contracts. The latest contracts involve important fleet upgrades, as the Navy tries to drag the jet’s systems into the 21st century.
Latest updates[?]: The US Navy awarded General Dynamics Electric Boat a $9.5 billion contract modification for the construction and test of the lead and second ships of the Columbia Class. The contract modifies a $5 billion deal awarded in 2017. It exercises an option to test the ships and to provide design and engineering support. „This modification to the integrated product and process development (IPPD) contract supports the fiscal 2021 construction start of the lead ship (SSBN 826) and advance procurement, advance construction, coordinated material buys and full construction of the follow hull (SSBN 827) in fiscal 2024“, the Pentagon said in a statement. The original contract was for design completion for the Columbia-class ballistic missile submarines, which are meant to replace the Navy's current force of 14 aging Ohio Class boats. The Columbia Class is an upcoming class of nuclear submarines. General Dynamic subsidiary Electric Boat in collaboration with Newport News Shipbuilding are construction the Columbia Class ballistic missile submarines (SSBNs) for the US Navy. Work under the contract modification will take place in Connecticut, Virginia and Rhode Island. Estimated completion will be by April 2030.
SSBN-X concept
The US Navy needs new SSBN nuclear missile submarines. Their existing Ohio Class boats will begin to retire at a rate of 1 hull per year, beginning in 2027, as they reach the end of their 42-year operational lifetimes. Hence SSBN-X, also known as the Ohio Replacement Program for now.
The first step toward recapitalization involved a new Common Missile Compartment and Advanced Launcher for current and future nuclear missiles. The next step involves finalizing a design that can serve effectively to 2080, without destroying the US Navy’s shipbuilding budget in the process. Good luck with that one, but they have to to try. The maintenance of the USA’s nuclear deterrent is too important, in a world where nuclear weapons are proliferating.
The path toward a hypersonic space plane has been a slow one, filled with twists and turns one would expect given the technological leap involved. Speeds of Mach 8+ place tremendous heat and resistance stresses on a craft. Building a vehicle that is both light enough to achieve the speeds desired at reasonable cost, and robust enough to survive those speeds, is no easy task.
Despite the considerable engineering challenges ahead, the potential of a truly hypersonic aircraft for reconnaissance, global strike/ transport, and low-cost access to near-space and space is a compelling goal on both engineering and military grounds. The question, as always, will be balancing the need for funding to prove out new designs and concepts, with risk management that ensures limited exposure if it becomes clear that the challenge is still too great. In October 2008, the US Congress decided that FALCON/Blackswift had reached those limits. That decision led to the program’s cancellation, though some activities will continue.
The B-52 Stratofortress remains the mainstay of the U.S. strategic bomber force, and in-theater combat communications improvements may allow it to make better use of advanced weapons like the JDAM. The B-52H, which went into service in 1961, is the only remaining B-52 model in use by the USAF. It flies slightly faster than a 767, operating at high subsonic speeds and altitudes up to 50,000 feet, and carrying either nuclear or precision-guided conventional weapons. On-going modifications have added global positioning system compatibility for the aircraft and weapons, targeting pods like the LITENING, heavy stores adapter beams for carrying 2,000 pound munitions, and an array of advanced weapons.
Under the B-52 combat network communications technology (CONECT) program, the B-52H fleet will receive new computers and color displays, key datalinks, an advanced wideband satellite terminal, and a series of tie-ins to existing USAF systems that will allow them to receive new missions, or even re-target weapons during flight. The total development contract originally projected $500 million worth of spending, but the Air Force announced an abrupt restructuring in its FY13 budget request. However that lasted all of 3 months, as a Milestone C decision came in May 2012, followed by the first production orders and a FY14 request putting these upgrades back on track, though with less money. A first delivery in April 2014 indicated the program seemed to settle down.
Rockwell Collins, Inc. of Cedar Rapids, Iowa received a cost plus award fee, firm-fixed price, cost plus fixed fee and time and material contract modification for $27.5 million. The award will “rebaseline” system development and demonstration completion, low rate initial production (LRIP), and production and deployment of the USA’s KG-3X cryptographic modernization program.
KG-3X units are used in the Minimum Essential Emergency Communications Network (MEECN) and the Fixed Submarine Broadcast System (FSBS) for strategic transmission of Emergency Action Messages (EAMs). The program entails box replacements, card set replacements, and reprogramming of 921 units Of these, 445 units will require organic service reprogramming, while industry will be contracted to handle 476 units. Funds will be allocated as needs arise by Air Force Materiel Command’s Electronic Systems Center, 653rd Electronic Systems Wing at Hanscom Air Force Base, MA (FA8722-04-C-0004, P00026).
The Headquarters 526th ICBM Systems Wing at Hill Air Force Base, UT has issued a pair of cost-plus fixed-fee contract modifications. Their R&D effort is aimed at technologies that might be used in a replacement to the third stage of the USA’s existing LGM-30 Minutemean III nuclear ICBMs. The 30+ year old missiles are undergoing upgrades that will keep them in service, now that the newer and more advanced MX Peacekeeper missiles have all been retired under arms control agreements. See all DID coverage of the Minuteman missiles.
Phase II involves detailed design test and manufacturing reviews of motor hardware to be fabricated. The reviews shall include detailed drawings, analysis, and any data generated to support the design of hardware to be test fired. The contractor will fabricate motor and test hardware and conduct any checkout testing identified in the preliminary Phase II test and instrumentation plan and coordinate test requirements with the Air Force. This action exercises the Phase II Option of the contract and implements a period of performance form 1 June 2006 through 31 May 2010.
ATK Thiokol Propulsion in Corinne, UT received $17.6 million (FA8204-06-C-0013/P00001)

Defense Update editor Tamir Eshel writes to let us know that Raytheon Company and Rafael Armament Development Authority have been selected by the Israel Ministry of Defense’ Defense Research and development Directorate (DDRD) to develop a new terminal missile defense interceptor for low-cost, short-range ballistic missile (SRBM) threats. Israeli planners see SRBMs as cheap, plentiful, easily concealed, largely exempt from international arms control accords, and capable of being transformed into deadly threats if/ when fitted with unconventional warheads and deployed in large quantities.
Accordingly, Israel and the US have agreed to jointly develop a new Short Range Missile Defense (SRMD) capability that will complement its existing Arrow and Patriot PAC-2 GEM+ systems, one optimized via its design and cost to defend against rockets with ranges of 70 – 200 km…
The Headquarters Ogden Air Logistics Center, Hill Air Force Base, UT has issued a pair of contracts to Northrop-Grumman Space and Mission Systems in Clearfield, UT. The contracts are related to the LM-30 Minuteman III Intercontinental Ballistic Missile (ICBM).
With the recent treaty-driven retirement of the more-modern MX Peacekeeper missiles, the Minuteman III missiles remain as the land-based leg of the USA’s nuclear triad. In order to keep them viable significant refits, upgrades, and other measures are underway. These two modifications are part of that effort, under contract # F42610-98-C-0001…
Northrop Grumman Mission Systems in Clearfield, UT received a $225.2 million cost-plus-incentive-fee, cost-plus-award-fee contract modification re: the intercontinental ballistic missile (ICBM) propulsion replacement program. Full Rate Production (FRP) options FRP5, FRP6, and FRP7 restructure modification for two-hundred and twelve (212) stage 1, 2 and 3 rocket motors, production quality assurance, ordnance production, and contractor cost data reports. Since this is the USA, the motors will be placed on its Minuteman III missiles as part of the overall modernization program to keep them in service. See all DID coverage related to the Minuteman III.
Negotiations were complete in May 2005, and work will be complete in March 2008. The Headquarters 528th ICBM Systems Wing at Hill Air Force Base, UT, issued the contract (F42610-98-C-0001, no modification number assigned yet).
Lockheed Martin Space Systems in Sunnyvale, CA received an $869 million cost-plus-incentive-fee, cost-plus-fixed-fee, cost-plus-award-fee contract from the US Navy to provide funding for fiscal 2006 Trident II (D5) Missile Production and Deployed System Support. The Trident D-5 is a very accurate submarine-launched nuclear missile, and can be found on the US Navy’s Ohio Class SSBNs and the Royal Navy’s Vanguard Class SSBNs. It is the most survivable, capable, and important facet of these nations’ nuclear deterrent forces.
So, where is all this money going? Didn’t America already buy the required missiles back in the 1980s-1990s, when it deployed the submarines?
