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…

JLTV: Oshkosh Wins, Lockheed Protests

In an age of non-linear warfare, where front lines are nebulous at best and non-existent at worst, one of the biggest casualties is… the concept of unprotected rear echelon vehicles, designed with the idea that they’d never see serious combat. That imperative is being driven home on 2 fronts. One front is operational. The other front is buying trends.

These trends, and their design imperatives, found their way into the USA’s Joint Light Tactical Vehicle (JLTV) program, which aims to replace many of the US military’s 120,000 or so Humvees. The US military’s goal is a 7-10 ton vehicle that’s lighter than its MRAPs and easier to transport aboard ship, while offering substantially better protection ad durability than existing up-armored Humvees. They’d also like a vehicle that can address front-line issues like power generation, in order to recharge all of the batteries troops require for electronic gadgets like night sights, GPS devices, etc.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. JLTV certainly qualifies, and recent budget planning endorsements have solidifed a future that was looking shaky. Now, can the Army’s program deliver?

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.

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.

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.

SSBN-X Subs: Congressmen Promote Refresh, Have Sub Bases in Districts

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.

Despite Problems, UK Moves Ahead with $376M Bowman Radio Upgrade

Bowman radios

The UK’s Bowman tactical communications system, which replaced the aging Clansman system, has encountered some problems with troops deployed in Afghanistan. The Bowman radios carried by the soldiers have a short battery life and are heavy. There is also a shortage of ancillary equipment, such as antennas and speakers, according to a May 14/09 report by the UK National Audit Office (NAO).

As DID reported earlier, a 2006 NAO report had identified a number of serious problems with the Bowman system resulting from the radical changes in communications technology and needs since the program was conceived in the 1980s. The report identified as issues the vast growth in bandwidth requirements due to UAVs et. al. transmitting video, the need for far greater capabilities without providing more money, the lack of robustness and modifiability in its closed architecture software systems, the effects of Bowman’s lack of definition on training and doctrine, and the effects of the program on the decimated British tactical radio industry.

Despite these problems, the UK Ministry of Defence (MOD) recently awarded 2 contracts worth £231 million ($376 million) to prime contractor General Dynamics UK to upgrade the Bowman system.

US Army Moves Ahead with V-Hull Strykers

M1126, post-IED

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.

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

“Slick 32”

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).

ATK’s Guided Mortars

ATK’s PGM

The US Army is pushing to get precision mortars developed and deployed to the field in Afghanistan as soon as possible. Mortars are lighter and can be towed by a HMMWV or MRAP, or carried and fired from inside M113 or Stryker APCs, making them easier to deploy than heavier cannon artillery.

When indirect fire support is needed against enemies who are dug in along mountain ridgelines and other high positions, or in an urban area where which building you hit matters a great deal, getting the job done requires precision artillery. That capability has already come to MLRS rockets (M30/31 GMLRS, ATACMS), and 155mm artillery shells (Excalibur), and has been deployed to great effect on the front lines by American forces and their allies. Now it is coming to the USA’s 120mm mortars as well.
