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.

AMRAAM: Deploying & Developing America’s Medium-Range Air-Air Missile

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.

One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade…

Super Hornet Fighter Family MYP-III: 2010-2014 Contracts

Breakthrough…

The US Navy flies the F/A-18 E/F Super Hornet fighters, and has begun operating the EA-18G Growler electronic warfare & strike aircraft. Many of these buys have been managed out of common multi-year procurement (MYP) contracts, which aim to reduce overall costs by offering longer-term production commitments, so contractors can negotiate better deals with their suppliers.

The MYP-II contract ran from 2005-2009, and was not renewed because the Pentagon intended to focus on the F-35 fighter program. When it became clear that the F-35 program was going to be late, and had serious program and budgetary issues, pressure built to abandon year-by-year contracting, and negotiate another multi-year deal for the current Super Hornet family. That deal is now final. This entry covers the program as a whole, with a focus on 2010-2015 Super Hornet family purchases. It has been updated to include all announced contracts and events connected with MYP-III, including engines and other separate “government-furnished equipment” that figures prominently in the final price.

IOTV: Interceptor’s Incremental Improvement

IOTV: key features

The USA’s Interceptor OTV (Outer Tactical Vest) Body Armor, and its SAPI/ESAPI ceramic plate inserts, offer a significant improvement over its 1990s predecessors in terms of both weight and protection. After episodic issues with production ramp-up and quality control, this gear is widely fielded with the US Army and several allied militaries (the US Marines replaced it with the MTV). In May 2007, controversy regarding the armor’s effectiveness boiled over in the wake of a TV news feature. The US Army responded with rare public claims about a competing product, even as several high-profile legislators advocated independent civilian tests to ensure that US soldiers were really getting the best system.

Meanwhile, improvements were being made to the OTV system in response to feedback from the field. Hence the Improved OTV, whose Generation II model is now in production.

AMDR: Raytheon is Building the USN’s Next Dual-Band Radar

DBR testbed, Wallops

The US Navy’s Dual-Band Radar that equips its forthcoming 14,500t Zumwalt class“destroyers” and Gerald R. Ford class super-carriers replaces several different radars with a single back-end. Merging Raytheon’s X-band SPY-3 with Lockheed Martin’s S-band VSR allows fewer radar antennas, faster response time, faster adaptation to new situations, one-step upgrades to the radar suite as a whole, and better utilization of the ship’s power, electronics, and bandwidth.

Rather than using the existing Dual-Band Radar design in new ships, however, the “Air and Missile Defense Radar” (AMDR) aimed to fulfill future CG (X)/ DG-51 Flight III cruiser needs through a new competition. It could end up being a big deal for the winning radar manufacturer, and for the fleet. If, and only if, the technical, power, and weight challenges can be mastered at an affordable price.

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.

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.

Heat Vision: US Teen Series Fighters Getting IRST

IRST: B-2, ICU

F/A-18 E/F Super Hornet Block IIs fighters are beginning to enter service with the US Navy and Australia, carrying significantly improved AN/APG-79 AESA radars and other electronic upgrades. Recent years have seen another spreading improvement within global fighter fleets, however: Infra-Red Search & Track (IRST) systems that provide long range thermal imaging against air and ground targets. Most of these deployments have been on Russian (MiG-29 family, SU-30 family) and European (Eurofighter, Rafale, Gripen NG) fighters, or special American exports (UAE’s F-16E/F Block 60 Desert Falcons, Korea & Singapore’s F-15K/SG Strike Eagles).

That absence puts American fighters behind an important curve. This IRST approach can defeat radar stealth in some instances, by focusing on engine exhaust, or on the friction of the aircraft as it powers through the atmosphere. As F-14 pilots will recall, long range electro-optics also offer positive identification, conferring the ability to use a plane’s aerial missiles at their full ranges. Best of all, IRST offers a passive way to locate and target enemy aircraft, without triggering the target’s radar warning receivers. When coupled with medium-range IR missiles like some Russian AA-10 variants, France’s MICA-IR, or even future versions of AMRAAM NCADE, an IRST system offers a fighter both an extra set of medium-range eyes, and a stealthy air-to-air combat weapon. Programs are underway to give some American “teen series” fighters this capability, albeit in a somewhat unusual way…

The Dutch JSS Multi-Purpose Support Ship

MvD’s JSS concept

In January 2010, Damen Schelde announced a contract from the Dutch Defence Materiel Organisation to build a 28,000t “Joint Logistic Support Ship” (JSS), which will become the HNLMS Karel Doorman. The vessel is scheduled to launch in 2014, and will replace the retired 16,900t HNLMS Zuiderkruis.

The Dutch wanted a very versatile ship that can resupply other warships, transport significant loads of army equipment and vehicles, act as a floating headquarters, take on hospital duties, and embark up to 6 helicopters. That level of versatility will come with costs. Canada’s ill-fated JSS program had similar or larger ambitions, but the 3-ship, C$ 2.9 billion program was ultimately suspended when contractors informed the government that they couldn’t supply what Canada wanted at the prices demanded. Can the Netherlands be more successful? So far, the answer is “yes”.
