AIM-9X Block II & Beyond: The New Sidewinder Missiles

Raytheon’s AIM-9X Block II would have made Top Gun a very short movie. It’s the USA’s most advanced short range air-air missile, capable of using its datalink, thrust vectoring maneuverability, and advanced imaging infrared seeker to hit targets behind the launching fighter. Unlike previous AIM-9 models, the AIM-9X can even be used against targets on the ground.

These changes will help keep it competitive against foreign missiles like MBDA UK’s AIM-132 ASRAAM, RAFAEL of Israel’s Python 5, the multinational German-led IRIS-T, and Russia’s R73/ AA-11 Archer. So far, only American fighter types can use AIM-9X missiles, but that hasn’t stopped a slew of export requests and sales, especially in the Middle East.

MH-60R/S: The USA’s New Naval Workhorse Helicopters

The US Army’s UH-60 Black Hawks have always had a naval counterpart. SH-60B/F Seahawk/ LAMPS helicopters were outfitted with maritime radar, sonobuoys, and other specialized equipment that let them perform a wide variety of roles, from supply and transport, to anti-submarine warfare, search and rescue, medical evacuation, and even surface attack with torpedoes or Kongsberg’s AGM-119 Penguin missiles. Like their land-based counterparts, however, the Seahawks are getting older. The Reagan defense build-up is receding into history, and its products are wearing out.

European countries chose to build new designs like the medium-heavy EH101 and the NH90 medium helicopter. They’re larger than the H-60s, make heavy use of corrosion-proof composites, and add new features like rear ramps. The USA, in contrast, decided to upgrade existing H-60 designs for the Army and Navy. Hence the MH-60R Multi-Mission Helicopter (aka. “Romeo”) and MH-60S (aka. “Sierra”) Seahawks. MH-60Rs and MH-60Ss will eventually replace all SH-60B/F & HH-60H Seahawks, HH-1N Hueys, UH-3H Sea Kings, and CH-46D Sea Knight helicopters currently in the US Navy’s inventory. Both programs are underway, and will be covered in this DID FOCUS Article.

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.

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.

Serious Dollars for AEGIS Ballistic Missile Defense (BMD)

The AEGIS Ballistic Missile Defense System seamlessly integrates the SPY-1 radar, the MK 41 Vertical Launching System for missiles, the SM-3 Standard missile, and the ship’s command and control system, in order to give ships the ability to defend against enemy ballistic missiles. Like its less-capable AEGIS counterpart, AEGIS BMD can also work with other radars on land and sea via Cooperative Engagement Capability (CEC). That lets it receive cues from other platforms and provide information to them, in order to create a more detailed battle picture than any one radar could produce alone.

AEGIS has become a widely-deployed top-tier air defense system, with customers in the USA, Australia, Japan, South Korea, Norway, and Spain. In a dawning age of rogue states and proliferation of mass-destruction weapons, the US Navy is being pushed toward a “shield of the nation” role as the USA’s most flexible and most numerous option for missile defense. AEGIS BMD modifications are the keystone of that effort – in the USA, and beyond.

RIM-162 ESSM Missile: Naval Anti-Air in a Quad Pack

The RIM-162 Evolved Sea Sparrow Missile (ESSM) is used to protect ships from attacking missiles and aircraft, and is designed to counter supersonic maneuvering anti-ship missiles. Compared to the RIM-7 Sea Sparrow, ESSM is effectively a new missile with a larger, more powerful rocket motor for increased range, a different aerodynamic layout for improved agility, and the latest missile guidance technology. Testing has even shown the ESSM to be effective against fast surface craft, an option that greatly expands the missile’s utility. As a further bonus, the RIM-162 ESSM has the ability to be “quad-packed” in the Mk 41 vertical launching system, allowing 4 missiles to be carried per launch cell instead of loading one larger SM-2 Standard missile or similar equipment.

This is DID’s FOCUS article for the program, containing details about the RIM-162 Evolved Sea Sparrow missile family, and contracts placed under this program since 1999. The Sea Sparrow was widely used aboard NATO warships, so it isn’t surprising that the ESSM is an international program. The NATO Sea Sparrow Consortium includes Belgium, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Portugal, Spain, Turkey, and the USA – as well as non-NATO Australia. Foreign Military Sales ESSM customers outside this consortium include Japan, Thailand, and the United Arab Emirates.

India’s Nuclear Submarine Projects

According to GlobalSecurity.org, India’s ATV (advanced technology vessel) program to build a nuclear-powered submarine began in 1974, and became a serious effort in 1985. The Federation of American Scientists’ December 1996 document “The Indian Strategic Nuclear Submarine Project: An Open Literature Analysis” remains one of the best single open sources on India’s program. Unfortunately, it was compiled over a decade ago and has become rather dated. That project has continued, and this DID Spotlight article continues to collect open source information on the ATV program.

More and more sources were claiming that a rented Russian Akula class boat would be operational as a training vessel by 2009. The concept was correct, but the date was not. A deadly accident during K-152 Nerpa’s sea trials delayed that project, and further complications pushed its hand-over date to 2012. As efforts to move the Nerpa into service continue, India has finally launched its indigenous nuclear sub Arihant, to begin sea trials and testing.

Sons of Sa’ar? Israel’s Next Generation Frigates

The 1,227t/ 1,350 ton Sa’ar 5 Eilat Class corvettes were built by Northrop Grumman in the 1990s for about $260 million each. It’s a decent performer in a number of roles, from air defense to anti-submarine work, to coastal patrol and special forces support. In 2006, the Israelis went looking for a next-generation vessel with better high-end capabilities. Six years later, Israel had nothing to show for its search. In the meantime, massive natural gas deposits have been discovered within Israel’s coastal waters, adding considerable urgency to their search.

The USA is Israel’s logical supplier, but given Israel’s size and cost requirements, the only American option was the Littoral Combat Ship. Israel pursued that option for several years, conducting studies and trying to get a better sense of feasibility and costs. Their approach would have been very different from the American Freedom Class LCS, removing the swappable “mission modules” and replacing them with a fixed and fully capable set of air defense, anti-ship, and anti-submarine weapons. In the end, however, the project was deemed to be unaffordable. Instead, Israel began negotiating with Germany, and reports now include discussions involving both South Korea, and a local shipyard.

Hobart Class Ships: Aussie Anti-Air Umbrella

Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with modern ships that can provide significantly better protection from air attack, integrate with the US Navy and other coalition partners, offer long-range air warfare defense for Royal Australian Navy task groups, and help provide a coordinated air picture for fighter and surveillance aircraft. Despite their name and focus, the ships are multi-role designs, with a “sea control” mission that includes area air defense, advanced anti-submarine operations, and the ability to fight other ships.

The Royal Australian Navy took a pair of giant steps in June 2007, when it selected winning designs for its keystone naval programs: Canberra Class LHD amphibious operations vessels, and Hobart Class “air warfare destroyers.” Spain’s Navantia made an A$ 11 billion clean sweep, winning both the A$ 3 billion Canberra Class LHD and the A$ 8 billion Hobart Class Air Warfare Destroyer contracts. The new AWD ships were scheduled to begin entering service with the Royal Australian Navy in 2013, but that date has now slipped to 2016 or so. A 2014 ANAO report examines why – and the answers aren’t pretty.

EA-18G Program: The USA’s Electronic Growler

The USA’s electronic attack fighters are a unique, overworked, and nearly obsolete capability. With the retirement of the US Air Force’s long-range EF-111 Raven “Spark ‘Vark,” the aging 4-seat EA-6B Prowlers became the USA’s only remaining fighter for radar jamming, communications jamming and information operations like signals interception [1]. Despite their age and performance limits, they’ve been predictably busy on the front lines, used for everything from escorting strike aircraft against heavily defended targets, to disrupting enemy IED land mine attacks by jamming all radio signals in an area.

All airframes have lifespan limits, however, and the EA-6B is no exception. The USA’s new electronic warfare aircraft will be based on Boeing’s 2-seat F/A-18F Super Hornet multi-role fighter, and has 90% commonality with its counterpart. That will give it decent self-defense capabilities, as well as electronic attack potential. At present, however, the EA-18G is slated to be the only dedicated electronic warfare aircraft in the USA’s future force. Since the USA is currently the only western country with such aircraft, the US Navy’s EA-18G fleet would become the sole source of tactical jamming support for NATO and allied air forces as well.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article describes the EA-18G aircraft and its key systems, outlining the program, and keeping track of ongoing developments, contracts, etc. that affect the program.
