The USA’s DDG-1000 Zumwalt Class Program: Dead Aim, Or Dead End?

67% of the fleet

DID’s FOCUS Article for the DDG-1000 Zumwalt Class “destroyer” program covers the new ships’ capabilities and technologies, key controversies, associated contracts and costs, and related background resources.

The ship’s prime missions are to provide naval gunfire support, and next-generation air defense, in near-shore areas where other large ships hesitate to tread. There has even been talk of using it as an anchor for action groups of stealthy Littoral Combat Ships and submarines, owing to its design for very low radar, infrared, and acoustic signatures. The estimated 14,500t (battlecruiser size) Zumwalt Class will be fully multi-role, however, with undersea warfare, anti-ship, and long-range attack roles. That makes the DDG-1000 suitable for another role – as a “hidden ace card,” using its overall stealth to create uncertainty for enemy forces.

True, or False?

At over $3 billion per ship for construction alone, however, the program faced significant obstacles if it wanted to avoid fulfilling former Secretary of the Navy Donald Winter’s fears for the fleet. From the outset, DID has noted that the Zumwalt Class might face the same fate as the ultra-sophisticated, ultra-expensive SSN-21 Seawolf Class submarines. That appears to have come true, with news of the program’s truncation to just 3 ships. Meanwhile, production continues.

Raytheon’s AGM-176 Griffin Mini-Missiles

Griffin-B launch

As UAVs proliferate, and the demands of counter-insurgency fights force militaries to look at arming new kinds of aircraft, a number of manufacturers and governments are looking to develop precision-guided “mini-missiles” and glide weapons. Raytheon’s 33+ pound, 42 inch long Griffin is a member of that class, and comes in 2 versions.

The Griffin-A version is currently in use as part of American roll-on armed kits for its C-130 Hercules transports. It’s dropped out of “gunslinger” tubes, providing precision firepower from the rear ramp. The Griffin B is a forward-firing weapon that can be launched from land, naval, or aerial platforms. Either way, the missile packs a 13 pound blast-fragmentation warhead, and uses a combination of GPS/INS and a semi-active laser seeker for guidance. Griffin-B is currently a candidate to equip the Littoral Combat Ship’s surface warfare module.

LCS & MH-60S Mine Counter-Measures Continue Development

Old school:
MH-53E & Mk-105 sled

The US Navy currently uses large CH-53/MH-53 helicopters and towed sleds to help with mine clearance work, but they hope to replace those old systems with something smaller and newer. The MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system adds an operator’s station to the helicopter cabin, additional internal fuel stores, and towing capability, accompanied by a suite of carried systems that can be mixed and matched. AMCM is actually 5 different air, surface and sub-surface mine countermeasures systems, all deployed and integrated together in the helicopter.

While the US Navy develops AMCM, and complementary ship-launched systems for use on the new Littoral Combat Ships, new minehunter ship classes like the Ospreys are being retired by the US Navy and sold. All in an era where the threat of mines is arguably rising, along with tensions around key chokepoints like the Suez Canal and Strait of Hormuz.

This article explains the components involved (AQS-20, ALMDS, AMNS, OASIS, RAMICS; COBRA, RMS, SMCM), chronicles their progress through reports and contracts, and provides additional links for research.

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, what the Navy wanted, the capabilities needed to perform primary naval missions, and what could be delivered for the sums available, have proven nearly irreconcilable. 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.

JDAM: A GPS-INS Add-on Adds Accuracy to Airstrikes

B-2 drops JDAM

Precision bombing has been a significant military goal since the invention of the Norden bomb sight in the 1920s, but its application remained elusive. Over 30 years later, in Vietnam, the destruction of a single target could require 300 bombs, which meant sending an appropriate number of fighters or bombers into harm’s way to deliver them. Even the 1991 Desert Storm war with Iraq featured unguided munitions for the most part. The USAF some laser and TV-guided weapons like Paveway bombs and Maverick missiles, but they were very expensive, and only effective in good weather. If precision bombing was finally to become a reality throughout the Air Force, a new approach would be needed. The Joint Direct Attack Munition (JDAM) became that alternative, an engine of military transformation that was also a model of procurement transformation.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This DID FOCUS Article looks at the transformational history of the JDAM GPS-guided bomb program, the ongoing efforts to bring its capabilities up to and beyond the level of dual-mode guidance kits like Israel’s Spice and Raytheon’s Enhanced Paveway, and the contracts issued under the JDAM program since its inception.[updated]

The Right to Bear Arms: Gunship Kits for America’s C-130s

USMC KC-130J

Special Operations Command’s AC-130H/U gunships can lay down withering hails of accurate fire, up to and including 105mm howitzer shells, in order to support ground troops.

The Marines also wanted heavy aircraft that could support their Leathernecks on the ground. The bad news was that the Corps could field about 45 KC-130J aerial tankers for the price of a 12-plane AC-130J squadron. Lighter options like the AC-27J “Stinger II” would probably tally similar costs, once R&D dollars were distributed among such a small fleet. Could the Marines change tack, and offer a modular weapon package that would let them arm their existing tankers as needed? Could armed KC-130Js offer limited fire support, while loitering over the battlefield and using their unique speed envelope to refuel helicopters and fast jets alike? The Harvest Hercules Airborne Weapons Kit (HAWK) program aims to do just that. It gives the USMC a far less capable convertible gunship option in Afghanistan, but the cost is about 2 orders of magnitude below a dedicated gunship fleet. Unsurprisingly, the next service to show interest in this concept was SOCOM itself.

NH90: Europe’s Medium Helicopter Contender

NH90: TTH & NFH

The NH90 emerged from a requirement that created a NATO helicopter development and procurement agency in 1992 and, at almost the same time, established NHIndustries (62.5% EADS Eurocopter, 32.5% AgustaWestland, and 5% Stork Fokker) to build the hardware. The NATO Frigate Helicopter was originally developed to fit between light naval helicopters like AW’s Lynx or Eurocopter’s Panther, and medium-heavy naval helicopters like the European EH101. A quick look at the NFH design showed definite possibilities as a troop transport helicopter, however, and soon the NH90 project had branched into 2 versions, with more to follow.

The nearest equivalent would be Sikorsky’s popular H-60 Seahawk/ Black Hawk family, but the NH90 includes a set of innovative features that give it some distinguishing selling points. Its combination of corrosion-proofing, lower maintenance, greater troop or load capacity, and the flexibility offered by that rear ramp have made the NH90 a popular global competitor.

As many business people discover the hard way, however, success can be almost as dangerous as failure. NH Industries has had great difficulty ramping up production fast enough to meet promised deliveries, which has left several buyers upset. Certification and acceptance have also been slow, with very few NH90s in service over a decade after the first contracts were signed. Booked orders have actually been sliding backward over the last year, and currently stand at 474 machines, on behalf of 14 nations.

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

Hydras & Hellfires

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.

Korea’s T-50 Family Spreads Its Wings

T-50 Golden Eagle

South Korea’s T-50 Golden Eagle family offers the global marketplace a set of high-end supersonic trainer and lightweight fighter aircraft. They’re hitting the international market at a good time: just as many of the world’s jet training fleets are reaching ages of 30 years or more, and high-end fighters are pricing themselves out of reach for many countries.

The ROK’s defense industry is advancing on all fronts these days. Its shipbuilding industry, one of the world’s busiest, is beginning to turn out its own LHDs, and even high-end KDX-III AEGIS destroyers. On the armored vehicle front, Korea’s XK2 tank and K9/K10 self propelled howitzer are beginning to win export orders, and its XK-21/KNIFV amphibious infantry fighting vehicle may not be too far behind. All fill key market niches, promising performance at a comparatively inexpensive price. Now its aerospace industry is in flight abroad with the KT-1 turboprop basic trainer, complemented by the T-50 jet trainer, TA-50 LIFT advanced trainer & attack variant, and FA-50 lightweight fighter.

The TA-50 and FA-50 are especially attractive as lightweight export fighters, and the ROKAF’s own F-5E/F Tiger II and F-4 Phantom fighters are more than due for replacement. The key question for the platform is whether it can find corresponding export sales.

JAGM: Joint Air-Ground Missile Again

JAGM infographic

The AGM-114 Hellfire missile remains a mainstay for the US military and its allies around the world, and efforts to replace it have repeatedly stalled. Oddly, the problems have been unrelated to successor cost or performance. Rather, the programs kept getting cut to pay for other things. The Hellfires were seen as good enough, even as guided 70mm rockets and small multi-mode glide bombs gained a foothold as alternative precision strike options.

The Joint Common Missile (JCM) returned from the procurement dead as JAGM, a program that has undergone several major changes within itself. While other air forces field fast-jet solutions like MBDA’s Brimstone, JAGM will initially be limited to helicopters and UAVs, as a dual-mode guidance upgrade to current model Hellfire missiles.
