Trident II D5 Missile: Keeping Up with Changing Times

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.

Virginia Pivot: The USA’s Multi-Year Block IV Sub Deal

A 5-year, $17 billion deal will build 10 Virginia Class Block IV fast attack submarines for the US Navy, bringing production to 2 boats per year at long last. The USA’s nuclear submarine fleet gives it unmatched flexibility, but it’s confronted with rising submarine numbers in China and around the Pacific, even as its Los Angeles Class submarines are beginning to exit the fleet. Aircraft carriers may dominate in peacetime, but as anti-ship missiles gain longer reach and greater lethality, and sensors improve, some analysts are coming to see submarines as the key to wartime naval power…

USN Ship Protection: From “Slick 32s” to SEWIP

The US Navy’s AN/SLQ-32 ECM (Electronic Countermeasures) system uses radar warning receivers, and in some cases active jamming, as the part of ships’ self-defense system. The “Slick 32s” provides warning of incoming attacks, and is integrated with the ships’ defenses to trigger Rapid Blooming Offboard Chaff (RBOC) and other decoys, which can fire either semi-automatically or on manual direction from a ship’s ECM operators.

The “Slick 32” variants are based on modular building blocks, and each variant is suited to a different type of ship. Most of these systems were designed in the 1970s, however, and are based on 1960s-era technology. Unfortunately, the SLQ-32 was notable for its failure when the USS Stark was hit by Iraqi Exocet missiles in 1987. The systems have been modernized somewhat, but in an era that features more and more supersonic ship-killing missiles, with better radars and advanced electronics, SLQ-32’s fundamental electronic hardware architecture is inadequate. Hence the Surface Electronic Warfare Improvement Program (SEWIP).

APKWS II: Laser-Guided Hydra Rockets in Production At Last

The versatile Hydra 70mm rocket family is primed for a new lease on life, thanks to widespread programs aimed at converting these ubiquitous rockets into cheap laser-guided precision weapons. Conversion benefits include cost, use on both helicopters and fighters, more precision weapons per platform, low collateral damage, and the activation of large weapon stockpiles that couldn’t be used under strict rules of engagement.

Firms all over the world have grasped this opportunity, which explains why strong competition has emerged from all points of the compass. America’s “Advanced Precision-Kill Weapon System (APKWS)” is one of those efforts, but the road from obvious premise to working weapon has been slow. After numerous delays and false starts since its inception in 1996, an “APKWS-II” program finally entered System Design and Development (SDD) in 2006. In 2010, it entered low-rate production, and it was fielded to the front lines in 2012. That date will still put APKWS on the cutting edge of battlefield technology, as a leading player in a larger trend toward guided air-to-ground rockets.

Virginia Block III: The Revised Bow

“GDEB Receives $148M as Virginia Class Lead Yard” described changes to the Virginia Class submarine’s design that are expected to reach 20% of the $200 million savings goal by the time orders for the versatile sea attack/ land attack/ special forces submarines rise to 2 per year, in 2012.

The bow changes cover the FY 2009-2013 ships, referred to as Block III. SSN 774 Virginia – SSN 777 North Carolina are Block I, and SSNs 778-783 will be Block II. Block III begins with the 11th ship of class, SSN 784. Long lead time component orders began May 22/08, and the submarine is expected to be ready for delivery around 2015. A fuller explanation of Block III’s extensive bow changes, and an accompanying graphic, may be found below – along with contract updates that include additional improvements and sonar development.

US Army Moves Ahead with V-Hull Strykers

Under current plans, the 8×8 wheeled Stryker armored vehicle will be the future backbone of 8 US Army and 1 National Guard medium armored brigades. The 5th Stryker Brigade from Fort Lewis, WA was the first Stryker unit sent to Afghanistan, deployed in the summer of 2009 as part of a troop level increase. The brigade was equipped with 350 Stryker vehicles. In the first few months of deployment, they lost 21 soldiers, with 40 more wounded, to IED land mines. The losses prompted the Army to examine modifications to their Stryker vehicles, in order to make them more resistant to land mines.

One result is the Stryker hull redesign, creating the v-hulled Stryker DVH. The US Army is now on pace to order 2 brigades worth, as it moves toward the end of Stryker armored vehicle production.

LCS: The USA’s Littoral Combat Ships

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $35+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, the Navy hasn’t been able to reconcile what they wanted with the capabilities needed to perform primary naval missions, or with what could be delivered for the sums available. The LCS program has changed its fundamental acquisition plan 4 times since 2005, and canceled contracts with both competing teams during this period, without escaping any of its fundamental issues. Now, the program looks set to end early. This public-access FOCUS article offer a wealth of research material, alongside looks at the LCS program’s designs, industry teams procurement plans, military controversies, budgets and contracts.

AW159 Wildcat: The Future Lynx Helicopter Program

In 2006, Finmeccanica subsidiary AgustaWestland received a GBP 1 billion (about $1.9 billion at 02/07 rates) contract from the UK Ministry of Defence (MoD) for 70 Future Lynx helicopters, and began a new chapter in a long-running success story. The Lynx is an extremely fast helicopter that entered service in the 1970s, and quickly carved out a niche for itself in the global land and naval markets. The base design has evolved into a number of upgrades and versions, which have been been widely exported around the world.

In Britain, Lynx helicopters are used in a number of British Army (AH7 & AH9) and Fleet Air Arm (Mk 8) roles: reconnaissance, attack, casualty evacuation & troop transport, ferrying supplies, anti-submarine operations, and even command post functions. The Future Lynx program reflects that, and British government and industry are both hoping that its versatility will help it keep or improve the Lynx family’s global market share. This is DID’s FOCUS Article for the AW159 Lynx Wildcat Program, describing its technical and industrial features, schedules, related contracts, and exports.

Canada’s CH-148 Cyclones: 4th Time Lucky?

Canada’s Maritime Helicopter Replacement Program has been a textbook military procurement program over its long history. Unfortunately, it has been a textbook example of what not to do. While Canada’s 50-year old Sea King fleet aged and deteriorated to potentially dangerous levels, political pettiness and lack of concern turned a straightforward off-the-shelf buy into a 25+ year long odyssey of cancellations, lawsuits, rebids, and more. Eventually, the Canadian military settled on Sikorsky’s H-92 Superhawk as the basis of its new CH-148 Cyclone Maritime Helicopter, which will serve from the decks of Canada’s naval ships and bases.

The civilian S-92 has gone on to some commercial success. To date, however, Canada has been the H-92’s only military customer – with all of the associated systems integration and naval conversion burdens that one would expect. After a long series of badly missed milestones and delivery delays, there are also deeper questions being raised concerning both the machines’ fitness, and DND’s conduct of the program as a whole. This article covers the rationale for, history of, and developments within Canada’s Maritime Helicopter Program.

The USA’s Spearhead-class, expeditionary fast transports

When moving whole units, shipping is always the cheaper, higher-capacity option. Slow speed and port access are the big issues, but what if ship transit times could be cut sharply, and full-service ports weren’t necessary? After Australia led the way by using what amounted to fast car ferries for military operations, the US Army and Navy decided to give it a go. Both services leased Incat TSV/HSV wave-piercing catamaran ship designs, while the Marines’ charged ahead with very successful use of Austal’s Westpac Express high-speed catamaran. These Australian-designed ships all give commanders the ability to roll on a company with full gear and equipment (or roll on a full infantry battalion if used only as a troop transport), haul it intra-theater distances at 38 knots, then move their shallow draft safely into austere ports to roll them off.

Their successful use, and continued success on operations, attracted favorable comment and notice from all services. So favorable that the experiments have led to a $3+ billion program called the Joint High Speed Vessel. These designs may even have uses beyond simple ferrying and transport.
