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

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 Canberra Class LHDs

In May of 2006 the Royal Australian Navy announced its decision to expand its naval expeditionary capabilities. HMAS Manoora and Kanimbla would be replaced with substantially larger and more capable modern designs, featuring strong air support. Navantia and Tenix offered a 27,000t Landing Helicopter Dock (LHD) design that resembled the Strategic Projection Ship (Buque de Proyeccion Estrategica) under construction for the Spanish Navy. The DCNS-Thales Australia team, meanwhile, proposed a variation of the 21,300t Mistral Class that is serving successfully with the French Navy.

Navantia’s larger design eventually won, giving the Spanish firm an A$ 11 billion clean sweep of Australia’s “Air Warfare Destroyer” and LHD programs. These 5 ships will be the core of Australia’s future surface navy. The future HMAS Canberra and HMAS Adelaide will be able to serve as amphibious landing ships, helicopter carriers, floating HQs and medical facilities for humanitarian assistance, and launching pads for UAVs or even short/vertical takeoff fighters.

The Dokdo Class: an LHD for the ROK

Australia isn’t the only Pacific Rim country looking to modernize its Navy these days. China’s rapid shipbuilding program and work on its aircraft carrier project gets a lot of attention – but just to the east, South Korea is fielding its own AEGIS-equipped “air warfare destroyer,” while picking up new capabilities via a new class of amphibious assault LHD ship. Sound familiar? Hobart and Canberra Class, meet the KDX-III King Sejong Class AEGIS destroyer (launched May 2007) and the new “LPH” Dokdo Class LHD (commissioned July 2007).

The 199-meter, 18,860-ton Dokdo Class officially has the less aggressive designation of LPH (landing platform, helicopter), but its well deck and amphibious assault capabilities place it within the LHD category…

CEC: Cooperative Engagement for Fleet Defense

Cooperative Engagement Capability (CEC) is the US Navy’s secret weapon. Actually, it’s not so secret. It’s just that its relatively low price means often leads people to overlook the revolutionary change it creates for wide-area fleet air and ballistic missile defense.

CEC is far more than a mere data-sharing program, or even a sensor fusion effort. The concept behind CEC is a sensor netting system that allows ships, aircraft, and even land radars to pool their radar and sensor information together, creating a very powerful and detailed picture that’s much finer, more wide-ranging, and more consistent than any one of them could generate on its own. The data is then shared among all ships and participating systems, using secure frequencies. It’s a simple premise, but a difficult technical feat. With huge implications.

This DID FOCUS Article explains those mechanics and implications. It will also track ongoing research, updates, and contracts related to CEC capabilities from 2000 forward.

The International Wideband Global SATCOM (WGS) Program

The US military needs a bigger data firehose. In an era of streaming data from proliferating UAVs and other persistent surveillance platforms, and the need for control of those systems anywhere in the world, bandwidth is almost as important as fuel. Commercial satellite communications (SATCOM) can fill some of the gaps, but it’s expensive, and may not be available when needed. The Wideband Gapfiller SATCOM (now Wideband Global SATCOM) program began as a way to ease these problems in the near term, but went on to become one of the twin pillars of US military communications, alongside the hardened AEHF constellation. Both satellite types expanded their roles after the super-high bandwidth T-SAT program was canceled. Instead, the USA is adding WGS and AEHF satellites in space, even as it makes both programs multi-national efforts here on earth.

WGS is a set of 13-kilowatt spacecraft based on Boeing’s model 702 commercial satellite. These satellites will handle a significant portion of the USA’s warfighting bandwidth requirements, supporting tactical C4ISR(command, control, communications, and computers; intelligence, surveillance, and reconnaissance); battle management; and combat support needs. Upon its 2007 launch into geosynchronous orbit, WGS Flight 1 became the U.S. Department of Defense’s highest capacity communication satellite. WGS F4, launched in January 2012, offers further improvements, as do satellites from WGS F8. The constellation is set to grow to 10, including international participation.

This is DID’s FOCUS Article covering the WGS program’s specifications, budgets, travails, international partnerships, and contracts, with links to additional research materials.

F-X2: Brazil’s Saab Contract for Gripen’s a Done Deal

As Brazil started boosting its defense budgets in past years, its Navy and Army received funds to replace broken-down equipment, while new fighters will be a critical centerpiece of the Forca Aerea Brasileira’s (FAB) efforts.

Boeing’s F/A-18 E/F Super Hornet, France’s Dassault’s Rafale, Saab’s JAS-39 Gripen NG were picked as finalists. But after repeated stalling, for years the question was whether Brazil would actually place an order, or fold up the competition like the ill-fated 2011 F-X process. At the end of 2013, Brazil unexpectedly picked the Swedish offer, thanks to its offsets, price, and lack of diplomatic baggage. An initial contract is now in place, and this Spotlight article takes you through the competition, choices, and ongoing developments in a country that seems likely to become the world’s largest Gripen fleet.

Reap and Sow… The British RAF’s MQ-9 RPAS

Britain decided to stand up a full Reaper flight in late 2007, after positive early experience with 3 unarmed MQ-9s in Afghanistan. The British initially saw the MQ-9 only as a high-end surveillance drone to complement their mid-range , and short-range Desert Hawk and RQ-11 Raven mini-UAVs. That changed, as the RAF eventually bought 10 Reapers – and armed them…

The USCG’s Legend Class National Security Cutters

The Legend Class National Security Cutters were the largest ships in the The US Coast Guard’s massive $25 billion Deepwater meta-program, and served as its flagship in more ways than one. The 418 foot, 4,400 ton ships will be frigate-sized vessels with a 21 foot draughts, and are rather larger than the 379 foot, 3,250 ton Hamilton Class High Endurance Cutters (HECs) they will replace. Controversies regarding durability and potential hull fatigue, as well as significant cost overruns, have shadowed the new cutter’s construction. The program has survived, and is pushing toward its end in a few years – but will the number of ships bought be enough to help the USCG?

This DID FOCUS Article covers the Legend Class cutters’ specifications, program history, and key events…

Double-Jointed & Popular: The Bv Family of Infantry Support Vehicles

The BvS10 is the successor to the wildly popular Bv206, 11,000 of which have been sold to 40 countries around the world – including the USA (M978). Readers may have seen these vehicles elsewhere, too, as a number of Bv206s have post-military careers at ski resorts, in industries like mining and logging, etc. The new BvS-10 is larger and more heavily armored; it’s in use in Britain, France and the Netherlands as a key armored vehicle for their respective Marines, has been bought by Sweden, and is under evaluation elsewhere. International interest includes imitators: Singapore’s Bronco ATTC is a BVS10 competitor, and Finland and Norway have their own local Bv206 variants.

What makes this unusual-looking vehicle family and design so popular? They aren’t like Humvees or similar wheeled mainstays. They aren’t full armored personnel carriers, either – they’re armored, but Bv family vehicles can’t take the kind of punishment that a Bradley or LAV can absorb. Instead, the secret to their success lies in a remarkable all-terrain capability, and their ability to fill a rare and critical role: air-portable and amphibious infantry enhancement. These success factors are discussed below, along with contracts and key developments related to this vehicle family.

One for All: AAI Textron’s UAV Control System (UGCS/OSVRT)

Can the Army create a universal ground control system for UAVs? The ability to use hundreds of comparatively cheap UAVs from different manufacturers has been a blessing to ground forces, who finally have the comprehensive aerial coverage they want. It can also be a curse. If each system has its own unique controller and vehicle – or worse, its own receiver and screen – the result will be chaos.

Enter AAI’s One System ground control offerings, which are a step toward a more universal future. This Spotlight article covers the One System concept, its ongoing development, its current reach, and future technology initiatives and requirements that will affect UAV ground control.
