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]

Australia’s Submarine Program in the Dock

Buoy oh buoy…

The January 2010 failure of a generator aboard HMAS Farncomb was just the latest in a long history of problems faced by its fleet of 6 Collins Class diesel-electric submarines – which have sometimes been reduced to just 1 operational vessel. That readiness issue presents an immediate financial headache for Australia’s government, and adds a longer-term challenge to the centerpiece of Australia’s future naval force.

With just 6 submarines in its fleet, Australia’s current deployment set-up leaves little room for error. Even a normal setup of 2 in maintenance, 2 for training but available if needed, and 2 on operations makes for a thin line, given Australia’s long coastline and sea lanes. Almost 15 years after the first Collins Class boat was delivered, they are still short of this goal. When crewing problems are added to the mechanical issues, the failings of its current fleet are creating sharp questions about the Australia’s 2009 White Paper plan to build 12 new diesel-electric fast attack submarines, as the future centerpiece of the 2030 Australian Navy.

How We Rollo: Return of the USN’s S-3 Vikings?

S-3B

During its 35 years of service, the Viking proved itself so versatile that its mission was called simply “Sea Control.” Conceived primarily for anti-submarine warfare (ASW) against Soviet submarines with long range anti-shipping cruise missiles, the S-3A entered service in 1974, and received a number of upgrades over their lifetimes. Roles filled included anti-submarine warfare, mine warfare, electronic reconnaissance and analysis, over-the-horizon targeting, surface surveillance, missile attack, and aerial refueling.

The USN’s Viking fleet was phased out in 2009, and their tanker and land attack missions were taken over by F/A-18 E/F Super Hornets. Fleet-borne anti-submarine capabilities now depend on slower and shorter-range helicopters like the MH-60R, despite global submarine proliferation and the growing range and lethality of submarine launched missiles. That brings the Vikings’ era to a close… or does it?

Canada’s CH-148 Cyclones: 4th Time Lucky?

CH-148 Cyclone

Canada’s Maritime Helicopter Replacement Program has been a textbook military procurement program over its long history. Unfortunately, it has been a textbook example of what not to do. While Canada’s 50-year old Sea King fleet aged and deteriorated to potentially dangerous levels, political pettiness and lack of concern turned a straightforward off-the-shelf buy into a 25+ year long odyssey of cancellations, lawsuits, rebids, and more. Eventually, the Canadian military settled on Sikorsky’s H-92 Superhawk as the basis of its new CH-148 Cyclone Maritime Helicopter, which will serve from the decks of Canada’s naval ships and bases.

The civilian S-92 has gone on to some commercial success. To date, however, Canada has been the H-92′s only military customer – with all of the associated systems integration and naval conversion burdens that one would expect. After a long series of badly missed milestones and delivery delays, there are also deeper questions being raised concerning both the machines’ fitness, and DND’s conduct of the program as a whole. This article covers the rationale for, history of, and developments within Canada’s Maritime Helicopter Program.

Taiwan’s Force Modernization: The American Side

Latest updates[?]: House bill gives Taiwan access to 4 used frigates, must now pass Senate; Taiwan only wants 2; Modernization Dashboards updated.

Despite China’s ominous military buildup across the strait, key weapons sales of P-3 maritime patrol aircraft, Patriot PAC-3 missiles, and diesel-electric submarines to Taiwan had been sabotaged by Taiwanese politics for years – in some cases, since 1997. The KMT party’s flip-flops and determined stalling tactics eventually created a crisis in US-Taiwan relations, which finally soured to the point that the USA refused a Taiwanese request for F-16C/D aircraft.

That seems to have brought things to a head. Most of the budget and political issues were eventually sorted out, and after a long delay, some major elements of Taiwan’s requested modernization program appear to be moving forward: P-3 maritime patrol aircraft, UH-60M helicopters, Patriot missile upgrades; and requests for AH-64D attack helicopters, E-2 Hawkeye AWACS planes, minehunting ships, and missiles for defense against aircraft, ships, and tanks. These are must-have capabilities when facing a Chinese government that has vowed to take the country by force, and which is building an extensive submarine fleet, a large array of ballistic missiles, an upgraded fighter fleet, and a number of amphibious-capable divisions. Chinese pressure continues to stall some of Taiwan’s most important upgrades, including diesel-electric submarines, and new American fighter jets. Meanwhile, other purchases from abroad continue.

The Saudis’ American Shopping Spree: F-15s, Helicopters & More

F-15S & weapons

In October 2010, talks that Saudi Arabia was negotiating a $30-60 billion arms package with the USA were made official with a full multi-billion request that included 84 F-15 Strike Eagles to replace the Kingdom’s Tornado strike aircraft and/or F-15A-D fighters, upgrades for another 70 planes, about 132 UH-60 Black Hawk utility and AH-64 attack helicopters, and armaments to equip them.

This article looks at those requests, their tie-ins, the issues that are part of these potential deals, and related follow-on requests. As is often the case with DSCA announcements, years can pass between the requests and the signed contracts, but these contracts have started to roll in, alongside other significant buys.

Desert Leopards: Germany Selling Heavy Armor to the Saudis?

Leopard 2A7+

In mid-2011 reports surfaced that Saudi Arabia was preparing to buy around 200 German Leopard 2A7+ main battle tanks. Those reports stirred serious controversy in Germany, and indirectly confirmed the existence of a sales request.

Saudi Arabia would hardly be the first recipient of new or refurbished German tanks; indeed, Germany has displayed a consistent policy of selling cheap used tanks to countries all around Europe, and far beyond. Saudi Arabia is a somewhat surprising customer, because of its traditional “dual buy” structure for its land forces equipment, but there are strong reasons for Germany to be very interested in closing a Saudi sale. At the same time, the concerns expressed by opposition members are not without foundation.

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

AIM-9X test, F-18C
(click for close-up)

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…

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.

US Carrier Pilots’ T-45 Training System

Do you feel lucky…?

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:
