Any subs around?
Nuclear submarines are extremely expensive, but they offer a very important advantage over conventional diesel. They can remain submerged until their shipboard provisions run out, while operating at full capacity. This is very different from diesel-electric submarines, which must come up periodically for air or “snorkel” near the surface to fuel their engines. Even modern air-independent propulsion systems can’t entirely remove this disadvantage, just lengthen undersea operations to a maximum of 2-3 weeks at significantly reduced speeds.
The problem is that surface and near-surface operations are an especially vulnerable time – many of history’s submarine kills have involved boats in this condition. A surfaced, snorkeling or periscoping submarine can be found by observation, but radar is a much better option. If, of course, one can tell the difference between the massive radar clutter generated by waves et. al., and the particular signatures of submarines that have a small air tube or periscope riding just above or very close to the surface. A fact that explains the latest contract related to the US Navy’s new MH-60R anti-submarine helicopter.
Lockheed Martin Systems Integration – Owego in Owego, NY received a $144 million modification, finalizing a previously awarded cost-plus-fixed-fee modification (N00019-08-C-0005) to a cost-plus-incentive-fee contract. This modification provides for the system design and development of the MH-60R Advanced Radar Periscope Detection and Discrimination System, to include design, development, integration and test. Work will be performed in Owego, NY (51%) and Farmingdale, NY (49%), and is expected to be complete in September 2013. Contract funds will not expire at the end of the current fiscal year. The Naval Air Systems Command, Patuxent River, MD manages this contract. See also subsequent NAVAIR release.

The American Competitiveness Institute (ACI) in Philadelphia, PA received a $99,999,000 indefinite-delivery/ indefinite-quantity contract for a Benchmarking and Best Practices Center of Excellence. Work will be performed in Philadelphia, PA next to the airport, and is expected to be complete in June 2013. This contract was competitively procured under solicitation N00014-08-R-0001 by The Office of Naval Research in Arlington, VA (N00014-08-D-0758).
The government’s regional Electronics Manufacturing Productivity Facility (EMPF) was privatized in 1995, and is now operated by ACI as the US Navy’s center of excellence in electronics manufacturing. The center focuses of industry/ academia/ government partnerships to develop, apply and transfer new electronics manufacturing technologies and processes. ACI lists BAE Systems, L3 Communications, and DRS among defense sector clients who have taken advantage of their services. ACI also operates the U.S. Army’s Electronics Sustainment Center (AESC), which is focused on a different mission: inserting commercial off the shelf (COTS) components into existing military electronics to extend their useful life, make maintenance easier, and reduce costs.
The purpose of this particular contract is in line with EMPF’s mission: “to identify, validate, benchmark, and facilitate the dissemination (sharing) of best-in-class practices, processes, methodologies, systems, and pre-competitiveness technologies. In doing so, enhance and promote communications, corporation, integration, and interdependency across the defense industry that will result in improvements in affordability and performance of defense platforms and weapon systems.”

IRIS-T on Gripen
(click to view larger)
IRIS-T (InfraRed Imaging System – Tail/thrust vector controlled) emerged after Germany pulled out of the joint US-UK-German ASRAAM program, following testing with its “new” East German MiG-29s and their AA-11/R-73 Archer SRAAMs. The Germans came to believe that ASRAAM’s entire philosophy was wrong, and sought to develop their own missile based on the A-11’s lessons. IRIS-T is now being developed by a multinational European consortium, whose in-house orders include Germany (1,250: Eurofighter and Tornado), Denmark (500, F-16s), Greece (350, F-16s), Italy (450, Eurofighter and Tornado), Netherlands (500, F-16s), and Spain (700, Eurofighter and F/A-18 Hornet). Consortium members Sweden and Norway are also expected to order IRIS-T; Saab’s JAS-39 Gripen serves as the missile’s test platform, and there is also talk of integrating the missile with the F-35 Lightning II.
Now, South Africa becomes the missile’s 2nd export customer, after Austria ordered 25 at the end of 2005 to equip its Eurofighters. On May 28/08, Diehl BGT announced that the South African Air Force has picked the IRIS-T short range air-to-air missile to equip their Gripen fighter aircraft “as an interim solution until the local missile development – the A Darter – will be operational.”
The IRIS-T missiles will become operational on SAAF Gripens in 2009, and a recent Engineering News article confirms that there will be local defense industry workshare requirements attached to the buy. This makes for some interesting dynamics, given that A-Darter is being developed as an IRIS-T competitor. Details regarding these offsets may be released at the Africa Aerospace and Defence 2008 in Cape Town, from September 17 – 21.

Another day at work
Benham Constructors, LLC in Oklahoma, OK received a $55.1 million firm-fixed price contract to construct an advanced metal finishing facility building with various plating equipment at Robins Air Force Base, GA, while relocating a ground support equipment maintenance facility. Robins AFB is a major maintenance hub for the USAF, and the largest industrial complex in Georgia.
Work is expected to be complete by July 29/10. 16 bids were solicited on Jan 19/07, and 4 bids were received by the U.S. Army Engineer District in Savannah, GA (W912HN-08-C-0031).

Hindustan Aeronautics’ Dhruv project aimed to create a light helicopter that was well suited to light helicopter roles in India’s range of weather and altitude conditions. The firm has supplied 76 Dhruvs to India’s armed forces, an armed version has been created, and another 159 are in production for India’s Army and Air Force as a complement to India’s derailed light helicopter competition. The Navy has declined to buy more Dhruvs for its own needs, however, saying that several aspects of the design were not up to naval requirements yet.
HAL signed an agreement with Israel Aircraft Industries in 2004 for global marketing of the helicopter, which contains IAI avionics and Snecma Turbomeca engines. Sales of 1-2 helicopters have been made to Israel, Nepal, and Bolivia for various roles, some Dhruv helicopters have reportedly been transferred to Myanmar by the Indian government, and civilian versions are flying in India and Peru. The helicopter has also been marketed in other places, such as Chile, where it lost to the Bell 412.
Now the Dhruv has reportedly won a $50.7 million Ecuadoran Air Force contract for 7 Advanced Light Helicopters in the face of competition from Israel’s Elbit Systems, EADS Eurocopter, and Russia’s Kazan. India’s Business Standard reports that HAL’s offer was about 32% lower than the second lowest bid, which as reportedly from Elbit Systems. The contract is expected within a few weeks, and the first helicopter will be delivered by HAL in 6 months.
