UK PM Teresa May has come under fire following news that ministers covered up a failed test of the Trident nuclear deterrent
weeks before a crucial Commons vote on the future of the £40 billion program. Previous tests have been publicized by the Government. Details of the test, which happened last July, still remain undisclosed to the public, and opposition MPs are calling for an inquiry into the incident.
Trident II D5 Test Launch
Nuclear tipped missiles were first deployed on board US submarines at the height of the Cold War in the 1960s, to deter a Soviet first strike. The deterrence theorists argued that, unlike their land-based cousins, submarine-based nuclear weapons couldn’t be taken out by a surprise first strike, because the submarines were nearly impossible to locate and target. Which meant that Soviet leaders could not hope to destroy all of America’s nuclear weapons before they could be launched against Soviet territory. SLBM/FBM (Submarine Launched Ballistic Missile/ Fleet Ballistic Missile) offered shorter ranges and less accuracy than their land-based ICBM (Inter-Continental Ballistic Missile) counterparts, but the advent of Trident C4 missiles began extending those ranges, and offering other improvements. The C4s were succeeded by larger Trident II D5 missiles, which added precision accuracy and more payload.
The year that the Trident II D5 ballistic missile was first deployed, 1990, saw the beginning of the end of the missile’s primary mission. Even as the Soviet Union began to implode, the D5’s performance improvements were making the Trident submarine force the new backbone of the USA’s nuclear deterrent – and of Britain’s as well. To ensure that this capability was maintained at peak readiness and safety, the US Navy undertook a program in 2002 to replace aging components of the Trident II D5 missile called the D5 Life Extension (LE) Program. This article covers D5 LE, as well as support and production contracts associated with the American and British Trident missile fleets.

The Israeli Air Force has tested a new self-protection system
on its Lockheed Martin C-130Js to protect from surface-to-air missiles. Once equipped with the updated self-protection package, the air force's new transporters will be able to operate in areas where terrorist groups have ready access to shoulder-launched heat-seeking missiles. At present, Israel operates four C-130Js, with plans to purchase three more.

The C-130 Hercules remains one of the longest-running aerospace manufacturing programs of all time. Since 1956, over 40 models and variants have served as the tactical airlift backbone for over 50 nations. The C-130J looks similar, but the number of changes almost makes it a new aircraft. Those changes also created issues; the program has been the focus of a great deal of controversy in America – and even of a full program restructuring in 2006. Some early concerns from critics were put to rest when the C-130J demonstrated in-theater performance on the front lines that was a major improvement over its C-130E/H predecessors. A valid follow-on question might be: does it break the bottleneck limitations that have hobbled a number of multi-billion dollar US Army vehicle development programs?
C-130J customers now include Australia, Britain, Canada, Denmark, India, Israel, Iraq, Italy, Kuwait, Norway, Oman, Qatar, Saudi Arabia, South Korea, Tunisia, and the United States. American C-130J purchases are taking place under both annual budgets and supplemental wartime funding, in order to replace tactical transport and special forces fleets that are flying old aircraft and in dire need of major repairs. This DID FOCUS Article describes the C-130J, examines the bottleneck issue, covers global developments for the C-130J program, and looks at present and emerging competitors.

Canadian-based firm Héroux-Devtek have been tapped by Saab to manufacture landing gear systems
for the Gripen E
fighter. Under the contract, the company will assemble and deliver landing gear equipment for 96 Gripen planes being developed for the Swedish and Brazilian air forces. Manufacture work will be conducted at the company's UK facilities and deliveries will commence next year.

As a neutral country with a long history of providing for its own defense against all comers, Sweden also has a long tradition of building excellent high-performance fighters with a distinctive look. From the long-serving Saab-35 Draken (“Dragon,” 1955-2005) to the Mach 2, canard-winged Saab-37 Viggen (“Thunderbolt,” 1971-2005), Swedish fighters have stressed short-field launch from dispersed/improvised air fields, world-class performance, and leading-edge design. This record of consistent project success is nothing short of amazing, especially for a country whose population over this period has ranged from 7-9 million people.
This is DID’s FOCUS Article for background, news, and contract awards related to the JAS-39 Gripen (“Griffon”), a canard-winged successor to the Viggen and one of the world’s first 4+ generation fighters. Gripen remains the only lightweight 4+ generation fighter type in service, its performance and operational economics are both world-class, and it has become one of the most recognized fighter aircraft on the planet. Unfortunately for its builders, that recognition has come from its appearance in Saab and Volvo TV commercials, rather than from hoped-for levels of military export success. With its 4+ generation competitors clustered in the $60-120+ million range vs. the Gripen’s claimed $40-60 million, is there a light at the end of the tunnel for Sweden’s lightweight fighter? In 2013 a win in Brazil started to answer that question.

Recent testing on board the USS John Paul Jones by the US Missile Defense Agency have successfully demonstrated
the ability of the Aegis
baseline 9.C1 to tackle against a “complex medium-range ballistic missile target. A salvo of two SM-6
Dual I interceptors was fired during the December 14 exercise, using their explosive warheads to defeat the target. Program officials will continue evaluating system performance based upon telemetry and other data obtained during the test.
The AEGIS Ballistic Missile Defense System seamlessly integrates the SPY-1 radar, the MK 41 Vertical Launching System for missiles, the SM-3 Standard missile, and the ship’s command and control system, in order to give ships the ability to defend against enemy ballistic missiles. Like its less-capable AEGIS counterpart, AEGIS BMD can also work with other radars on land and sea via Cooperative Engagement Capability (CEC). That lets it receive cues from other platforms and provide information to them, in order to create a more detailed battle picture than any one radar could produce alone.
AEGIS has become a widely-deployed top-tier air defense system, with customers in the USA, Australia, Japan, South Korea, Norway, and Spain. In a dawning age of rogue states and proliferation of mass-destruction weapons, the US Navy is being pushed toward a “shield of the nation” role as the USA’s most flexible and most numerous option for missile defense. AEGIS BMD modifications are the keystone of that effort – in the USA, and beyond.
