E-2D Hawkeye: The Navy’s New AWACS

Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. Secondary roles include strike command and control, land and maritime surveillance, search and rescue, communications relay, and even civil air traffic control during emergencies. E-2C Hawkeyes began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. Over 200 Hawkeyes have been produced.

The $17.5 billion E-2D Advanced Hawkeye program aims to build 75 new aircraft with significant radar, engine, and electronics upgrades in order to deal with a world of stealthier cruise missiles, saturation attacks, and a growing need for ground surveillance as well as aerial scans. It looks a lot like the last generation E-2C Hawkeye 2000 upgrade on the outside – but inside, and even outside to some extent, it’s a whole new aircraft.

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.

US Carrier Pilots’ T-45 Training System

The T-45 Training System includes T-45 Goshawk aircraft, advanced flight simulators, computer-assisted instructional programs, a computerized training integration system, and a contractor logistics support package. The integration of all 5 elements is designed to produce a superior pilot in less time and at lower cost than previous training systems.

The US Navy uses the Hawk-based T-45TS system to train its pilots for the transition from T-6A Texan II/ JPATS aircraft to modern jet fighters – and carrier landings. This is not a risk-free assignment, by any means. Nevertheless, it is a critical link in the naval aviation chain. This DID FOCUS article covers the T-45TS, and associated contracts to buy and maintain these systems, from 2006 to the end of FY 2014.

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?

Global F/A-18 Hornet Fleets: Keeping ‘Em Flying

The F/A-18 Hornet is the F/A-18 E/F Super Hornet‘s predecessor, with the first models introduced in the late 1970s as a spinoff of the USAF’s YF-17 lightweight fighter competitor. Hornets are currently flown by the US Marine Corps as their front-line fighter, by the US Navy as a second-tier fighter behind its larger F/A-18 E/F Super Hornets, and by 7 international customers: Australia, Canada, Finland, Kuwait, Malaysia, Spain, and Switzerland. The USA’s aircraft were expected to have a service life of 20 years, but that was based on 100 carrier landings per year. The US Navy and Marines have been rather busy during the Hornets’ service life, and so the planes are wearing out faster.

This is forcing the USA to take a number of steps in order to keep their Hornets airworthy: replacing center barrel sections, re-opening production lines, and more. Some of these efforts will also be offered to allied air forces, who have their own refurbishment and upgrade programs.

P-3 Orion’s SMIP Program Keeps on Rolling

The P-3 Orion remains the USA’s main maritime patrol aircraft, and is also finding use in overland surveillance roles despite the fleet’s age. Earlier DID articles have noted the extra effort required to preserve the USA’s P-3C Orion maritime surveillance & patrol aircraft, along with radar and weapons upgrades to improve the fleet. Lockheed has even opened a new production line, to deal with planes whose wings that are so aged and worn that they need a full replacement.

The SMIP (Sustainment, Modification, and Installation Program) is intensive depot-level inspection and repair process that includes P-3 airframe and component inspection, identification of problems, and corrective maintenance. The idea is to ensure safe and reliable P-3 use, while trying to get more hours out of each airframe in order to sustain dwindling global fleets. More intensive “MIP” efforts may be launched once inspection results become clear, such as the USA’s P-3 recovery plan and full “ASLEP” re-winging efforts underway in Norway and Canada.

Snakes and Rotors: The H-1 Helicopter Program

The US Marines’ helicopter force is aging at all levels, from banana-shaped CH-46 Sea Knight transports that are far older than their pilots, to the 1980s-era UH-1N Hueys and AH-1W Cobra attack helicopters that make up the Corps’ helicopter assault force. While the tilt-rotor V-22 Osprey program has staggered along for almost 2 decades under accidents, technical delays, and cost issues, replacement of the USMC’s backbone helicopter assets has languished. Given the high-demand scenarios inherent in the current war, other efforts are clearly required.

Enter the H-1 program, the USMC’s plan to remanufacture older helicopters into new and improved UH-1Y utility and AH-1Z attack helicopters. The new versions would discard the signature 2-bladed rotors for modern 4-bladed improvements, redo the aircraft’s electronics, and add improved engines and weapons to offer a new level of performance. It seemed simple, but hasn’t quite worked out that way. The H-1 program has encountered its share of delays and issues, but the program survived its review, and continued on into production and deployment.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article covers the H-1 helicopter programs’ rationales and changes, the upgrades involved in each model, program developments and annual budgets, the full timeline of contracts and key program developments, and related research sources.

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.

UH-72 Lakota Light Helicopter Lands Airbus in US Defense Market

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This is DID’s FOCUS Article regarding the US Army’s Light Utility Helicopter program, covering the program and its objectives, the winning bid team and industrial arrangements, and contracts.

The US Army’s LUH program will finish as a 325 helicopter acquisition program that will be worth about $2.3 billion when all is said and done. It aimed to replace existing UH-1 Hueys and OH-58 Kiowa utility variants in non-combat roles, freeing up larger and more expensive UH-60 Black Hawk helicopters for front-line duty. In June 2006, a variant of Eurocopter’s EC145 beat AgustaWestland’s AB139, Bell-Textron’s 412EP Twin Huey, and MD Helicopters’ 902 Explorer NOTAR (No Tail Rotor) design. The win marked EADS’ 1st serious military win in the American market, and their “UH-145” became the “UH-72A Lakota” at an official December 2006 naming ceremony.

Eurocopter has continued to field new mission kits and deliver helicopters from its Mississippi production line, while trying to build on their LUH breakthrough. A training helicopter win will keep the line going for a couple more years…

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).
