General Dynamics Land Systems UK has commenced live firing trials
for its AJAX armored vehicle program
. The trials are being held in West Wales, Great Britain, and will last for approximately five months, starting with static firing positions against immobile point targets and gradually progressing to a moving vehicle engaging moving targets. It is armed with the CT 40 autocannon and a coaxial 7.62mm chain gun for lighter targets. Used by both the UK and French armed forces, the CT 40 ustilizes a type of telescoping 40mm ammunition designed to take up less space and reduce the necessary size of the gun. It can fire armor-piercing discarding sabot and high-explosive airburst ammunition out to an effective range of 2500 meters. It has a maximum rate of fire of up to 200 rounds per minute.
Many of Britain’s army vehicles are old and worn, and the necessities of hard service on the battlefield are only accelerating that wear. The multi-billion pound “Future Rapid Effects System” (FRES) aims to recapitalize the core of Britain’s armored vehicle fleet over the next decade or more.
The best one can say is that FRES has gone far better than America’s comparable and canceled “Future Combat System.” That doesn’t mean the rise has been smooth. FRES was spawned by the UK’s withdrawal from the German-Dutch-UK Boxer MRAV modular wheeled APC program, in order to develop a more deployable vehicle that fit Britain’s exact requirements. Those initial requirements were challenging, however, and experience in Iraq and Afghanistan led to decisions that changed an already-late program. So, too, have subsequent budgetary crises…

Lockheed Martin has received a $27 million modification
to an existing US Navy contract for the supply of retrofitting kits for the 60 Automatic Radar Periscope Detect and Discrimination (ARPDD) program. The firm will deliver 11 standard and 5 SEED kits for the program, which will provide a series of radar upgrades for use on MH-60 Seahawk
helicopters to help spot and discriminate enemy submarine periscopes. Work will primarily take place in Farmingdale, NY and Oswego, NY, with completion by October 2020. ARPDD has been in use with the Navy since 2009 and upgraded several times since then. It is one of the few systems available that are capable of identifying and tracking submarine periscopes.
USN Heli Plan
The US Army’s UH-60 Black Hawks have always had a naval counterpart. SH-60B/F Seahawk/ LAMPS helicopters were outfitted with maritime radar, sonobuoys, and other specialized equipment that let them perform a wide variety of roles, from supply and transport, to anti-submarine warfare, search and rescue, medical evacuation, and even surface attack with torpedoes or Kongsberg’s AGM-119 Penguin missiles. Like their land-based counterparts, however, the Seahawks are getting older. The Reagan defense build-up is receding into history, and its products are wearing out.
European countries chose to build new designs like the medium-heavy EH101 and the NH90 medium helicopter. They’re larger than the H-60s, make heavy use of corrosion-proof composites, and add new features like rear ramps. The USA, in contrast, decided to upgrade existing H-60 designs for the Army and Navy. Hence the MH-60R Multi-Mission Helicopter (aka. “Romeo”) and MH-60S (aka. “Sierra”) Seahawks. MH-60Rs and MH-60Ss will eventually replace all SH-60B/F & HH-60H Seahawks, HH-1N Hueys, UH-3H Sea Kings, and CH-46D Sea Knight helicopters currently in the US Navy’s inventory. Both programs are underway, and will be covered in this DID FOCUS Article.

Advanced construction has commenced on the US Navy's third Gerald R. Ford-class
aircraft carrier by Huntington Ingalls. The firm's Newport News Shipbuilding division started the process
last Thursday with a ceremonial cutting of a 35-ton steel plate of the Enterprise (CVN 80) under an advance-fabrication contract awarded earlier in the year. The Navy expects to make an award for the ship's detail design and construction next year.
USA’s Nimitz Class &
UK’s Invincible Class
Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.
Nimitz Class cutaway
As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.
DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.
