Preening the Hawks: Maintaining Australia’s H-60 Helicopters

Rescue me…

Australia may be an NH90 customer, but they also fly quite a few Sikorsky helicopters. Their 35 S-70A-9 Black Hawks began service in 1986, and have been used domestically and in a number of international deployments. Their lack of full defensive systems has prevented deployment to dangerous conflict zones like Afghanistan, but recent upgrades have partly fixed this problem. The Royal Australian Navy’s fleet of 16 S-70B-2 Seahawk helicopters contain features from the US Navy’s SH-60B and SH-60F Seahawks, and were delivered from 1988-1992. They will be replaced from 2016 onward by new MH-60R Seahawk helicopters.

Those fleets need maintenance, and Australia has signed a number of long-term contracts to that end. This article covers those contracts, from 2009 onward.

DARPA’s THz Electronics Program

THz flow

In 2009, the US Defense Advanced Research Projects Agency (DARPA) began awarding contracts for innovative research proposals under its Terahertz (THz) Electronics Program. Readers will probably be asking the same question that crossed our minds, namely, “when can I expect this, instead of my 2 GHz laptop?”

If Moore’s Law continues, the answer is somewhere between 2025 – 2030. The military thinks “why wait?”, and DARPA has a long history of helping to fund computing breakthroughs – from that minor nuisance we call the Internet to modern work on Gallium Nitride (GaN) semiconductors, non-thermionic transistors, research into graphene circuits, and more. Now, their Terahertz (THz) Electronics program is looking for technologies to enable revolutionary advances in electronic devices and integrated circuits, allowing them to reach THz frequencies (at least a trillion cycles per second).

Rapid Fire July 31, 2012: No WARN Act

• The US Labor Department issued guidance [PDF] on the application of the WARN Act in advance of sequestration. They are saying defense contractors with contracts at stake should not send WARN Act notices, contrarily to the position held by Lockheed Martin and others. They argue that while “it is currently known that sequestration may occur, it is also known that efforts are being made to avoid sequestration.” It is a bizarre line of reasoning given that executing sequestration next January is currently signed law. Perhaps knowing this, the Dept of Labor also argues that because DoD hasn’t announced which contracts would be affected, potential layoffs are speculative.

• Lockheed Martin has delivered the 8th C-5M Super Galaxy to the USAF.

• It may come in handy for moving blast-resistant MRAP vehicles from Afghanistan to their projected staging & storage areas, in Italy and the Western Pacific. Given North Korea’s known intent to use massive commando infiltration, MRAPs seem like a smart tactical choice in Korea.
