In “Hydra-70 Rockets: From Cutbacks to the Future of Warfare,” Sen. Leahy’s [D-VT] work to keep the Hydra 70mm rocket family alive through special appropriations was discussed, just in time for the Hydras’ potential on the battlefield to rise again. The key was the addition of low-cost precision guidance, which would expand the number of precision weapons carried by helicopters, aircraft, and even UAVs. “APKWS II… Hydra Rockets Enter SDD Phase,” discussed a laser-guided version from BAE, General Dynamics, and Northrop Grumman that appeared to have the inside track as a precision weapon of choice for helicopters, UAVs, and aircraft. This proved true, and the team won that contract in April 2006.

A lot can change in a couple of years. A lot has. This second attempt at APKWS has seen its program status change, before righting the program with Navy funding. Meanwhile, private development efforts from Lockheed Martin, Thales TDA, and a raft of international partnerships between major defense firms and partners in Korea, the UAE, Canada and Norway, and Israel are introducing new competitors into the precision-guided 70mm rocket space. The latest updates include successful tests of Elbit/ATK’s 70mm GATR system, and of a USMC program to retrofit its larger Zuni rockets…

IRST: B-2, ICU
(click to view full)

The F/A-18 E/F Super Hornet Block IIs are just beginning to enter service, with significantly improved AN/APG-79 AESA radars and other electronic upgrades. Recent years have seen another spreading improvement within global fighter fleets, however: Infa-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) fighters, or special American exports (UAE’s F-16E/F Block 60s, F-15K/SG).

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 missiles to their full ranges, without creating friendly fire concerns. Best of all, IRST offers a passive way to locate and target enemy aircraft – one that won’t trigger 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.

A program is beginning that would give American “teen series” fighters this capability, albeit in a somewhat unusual way…

Hydra-70 is a family of unguided rockets offering a variety of warhead configurations, from smoke and illumination rounds, to flechettes (hundreds of anti-personnel darts), submunition carriers, and unitary warheads up to 317 pounds. These versatile and relatively inexpensive rockets can be fired from a variety of aircraft, from attack helicopters to jet fighters to light helicopters like the OH-6 Little Bird, the new Bell 407 ARH, et. al. Hydra-70s have seen use in Afghanistan and Iraq, and they are arguably the world’s most widely used helicopter-launched weapon system. Magellan’s 70mm CRV-7 rockets and Thales’ 68mm SNEB system are its main Western competitors, while countries using Russian equipment have a variety of choices that begin with the 57mm S-5 family, extending through the 80mm S-8 family, and continuing up to the 266mm S-25.

While 70mm Hydra rockets are low cost weapons, and easy to carry in numbers, they are not a very accurate weapons system by modern standards. This makes them problematic choices for urban warfare if limitations exist on the use of force, and sharply limits their value to platforms like UAVs. The US Army intended to scale back production of the rocket system in 2003, but Congress, led by Senator Leahy’s [D-VT] efforts, reversed the decision with a $900 million contract.

Production continues under that contract, even as technology developments promise to make Hydra rockets a multi-headed battlefield threat once again…

DBR on CVN-21
(click to view full)

The US Navy’s newest light cruiser and aircraft carrier designs offer a wide array of new technologies. One is the Dual-Band Radar (DBR) system, which can be scaled up or down for installation in the new DDG-1000 Zumwalt Class “destroyers”, and the CVN-21 Gerald R. Ford Class aircraft carriers.

The DBR concept involves a significant change from current naval design approaches, and that change is not without risk. The USA’s GAO audit office has identified it as a significant risk to on-time fielding of the USS Zumwalt [DDG 1000], and any more development or testing snags could widen those impacts to include other ships. The radar is beginning to move from design to production, however, following a successful full-power “lightoff” of both DBR radars in an early April 2009 test.

The latest development involves a significant production contract for one of the DBR’s modules…

UK Phalanx at night
(click to view full)

The Mk15 Phalanx system was originally developed as a ship’s final hope against incoming missiles: a radar-guided 20mm gatling gun would would fire up to 6,000 rounds per minute, throwing up a last-ditch wall of lead. Phalanx has become a popular naval weapon that’s also effective against helicopters, UAVs, and even small boats. It has even migrated onto land, where its “Centurion” version can protect a 1.2 km square area against incoming mortars and rockets.

In September 2007, Jane’s reported from the British DSEi exhibition that Raytheon is working on a Phalanx variant that can fire lasers. Kevin Peppe, Raytheon’s Phalanx program director, said that:

“The Centurion system has provided a near-term C-RAM (Counter-Rocket, Artillery and Mortars) solution for our deployed forces. But we know that our customers would like a larger defended footprint beyond the kinematics of a gunbased system. A missile is too expensive, so we are looking instead at a solution based on the adaptation of a robust but relatively lowpower, low beam-quality commercial laser…. By using clever optics to focus the laser beam at range, we demonstrated that we could achieve sufficient energy on target to deflagrate a 60mm mortar round.”

The concept has promise – but it also has substantial obstacles to overcome before it can become militarily useful…

As UAVs begin to take on a wider array of battlefield roles, the ability to carry radars for situational awareness, detection, and targeting will become more and more important. Radars are also important to UAVs’ current functions as long-endurance ground surveillance platforms, however, offering an option that can supplement visual and thermal optics in order to penetrate foliage, and scan over a wider field of view. Many medium and large size tactical UAVs carry them now, from the General Atomics AN/APY-8 Lynx that can equips the MQ-1/9 Predator family, to the 65 pound Thales I-Master that equips Britain’s Hermes Mk450B Watchkeeper UAVs, to the tiny 2-pound NanoSAR radar that Boeing has tested on its small ScanEagle UAV.

France DGA recently announced a tri-national SIMCLAIRS program (Studies for Integrated Multifunction Compact Lightweight Airborne Radars & Systems) research program aimed at keeping European industry competitive in this area….

Global simulation firm CAE, located in the the Saint-Laurent district of Montreal, Canada, has announced a C$ 714 million (about $450 million equivalent), 5-year “Project Falcon” to enhance its modeling and simulation technologies, develop new ones, and diversify into other visualization markets including analysis and operations.

Aerospace is a major industry in Canada, but the size of Canada’s population and market ensures that over 80% of the industry’s business comes from exports. Hence the province of Quebec’s recent moves to assist Pratt & Whitney Canada with engine development, and the federal Strategic Aerospace and Defence Initiative (SADI) for strategic industrial research and R&D in the aerospace, defence, space and security industries. For CAE’s Project Falcon, SADI will provide a 6-year, C$ 250 million (about $200 million equivalent) repayable loan.

Project Falcon will focus on applying investments into 6 main technology thrusts, including…

HMMWV, IEDed
(click to view full)

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 that do not need to be designed for combat. That imperative is being driven home on 2 fronts.

One front is operational. IED land mines have been the #1 killer of American troops in Iraq, and up-armoring flat-bottomed Humvees proved to be an inadequate response. This finally led to the MRAP program at the end of 2006, which will have ordered and produced nearly 16,000 blast-resistant vehicles in less than 3 years. British experience in Iraq and Afghanistan has been similar, with 1/8 of all its casualties inflicted on troops riding in poorly-protected Land Rover Snatch jeeps. Those conditions have prompted several senior officer resignations in protest, including highly placed SAS commanders.

The other front is buying trends. While some countries like Australia and Germany were foresighted enough to develop and field mine-resistant vehicles before 2001, a collective realization is sinking in across the board that up-armoring flat-bottomed vehicles with inadequate carrying capacity, in order to provide a level of protection that is better but still poor, simply will not do. Future patrol vehicles will need to be designed from the outset for blast-resistance against land mines and even car bombs.

These 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 Hummers as its main tactical vehicle in combat zones. The military’s goal is a 7-10 ton vehicle that’s lighter than the MRAPs and easier to transport aboard ship, while offering substantially improved protection over existing up-armored Hummers. 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. The end of October 2008 saw 3 contract awards out of 7 qualifying submissions, which will be developed over the next 27 months into rival designs for the JLTV’s systems design and development phase.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. JLTV certainly qualifies, though its future remains cloudy due to expected spending cutbacks and the possible presence of “good enough” substitutes. Australia is currently a JLTV participant, a fact that was recently the focus for political controversy…

On Feb 19/09, the Australian Government formally opened an A$ 85 million Defence Materials Technology Centre (DMTC) in Bendigo, Victoria, aimed at researching futuristic materials for the Defence industry. The DMTC is the first center to be established under the Defence Future Capability Technology Centre Program, and the project was announced in December 2007. It’s funded under a partnership arrangement, with the Australian Government provided A$ 30 million. Collaborating partners contribute a further A$ 52-55 million.

The center currently has 16 projects underway, grouped into 4 broad categories. A pair of joint US-Australian programs also look set to benefit directly: the JLTV program for blast-resistant patrol vehicles, and their joint research program into hypersonic flight. The categories include:

F-35A: Dutch treat?
(click to view full)

The Netherlands is a notable player in the multinational F-35 program, as one of only two Tier 2 program partners, and the future site of a European maintenance hub. The government is still deciding whether it will join the Joint Strike Fighter’s IOTE phase and purchase 2 aircraft. Meanwhile, what was once a slam-dunk to replace RNLAF F-16s has now become a competition of sorts involving Saab’s JAS-39NG Gripen. To this point, the Dutch have invested over EUR 850 million in the F-35’s development phases.

The financing arrangements involved are highly unusual. They have now become a subject of possible legal action, as the government insists that industry players owe it more than EUR 300 million…
