The US Navy has awarded
Initial Operational Capability (IOC) to the service's latest airborne mine detection system, the AN/DVS-1 Coastal Battlefield Reconnaissance and Analysis (COBRA
). The system can be integrated on the MQ-8 Fire Scout
unmanned air system and can detect and localize minefields and obstacles when flown over a beach zone area, keeping sailors and marines out of harms way on a potential landing zone. Part of the littoral combat ship’s (LCS
) suite of mine countermeasures (MCM) systems, COBRA's next test will involve at-sea trails onboard a LCS vessel equipped with a full MCM package, where it will fly various missions over beaches, while demonstrating system suitability for operating from the LCS.
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.

Teledyne Brown Engineering, Inc., in Huntsville, AL recently received approval from the U.S. Navy to move into the Full Rate Production (FRP) Phase on the underwater Littoral Battlespace Sensing-Glider (LBS-G) Program. The first Full Rate Production option calls for the manufacture of 35 gliders, with additional options for 100 more, and a total contract value of $53.1 million if all options are exercised. US Space and Naval Warfare Systems Command manages the contract.
The Teledyne Team has already delivered 15 Low Rate Initial Production LBS-Gs to the US Navy’s Program Executive Office for C4I, under a December 2010 contract. That team includes Teledyne Brown (System Integration), Teledyne Webb Research in East Falmouth, MA (Slocum Glider development and production), and the University of Washington – Applied Physics Lab (Glider Operations Center software). Their 2m long design features a very innovative propulsion concept.

RSN project concept
The Applied Physics Laboratories at the University of Washington in Seattle, WA received a $120.4 million cost-plus-fixed-fee, indefinite-delivery/ indefinite-quantity task order contract for up to 657,115 staff hours. Multiple appropriation types will be utilized throughout contract performance, and no funds are obligated by award of this contract, only on individual task orders. A contract option could bring the cumulative value of this contract to $257.4 million for up to 1,314,230 staff hours. Work will be performed in Seattle, WA, and is expected to be complete by April 2015. This contract was not competitively procured by the Naval Sea Systems Command in Washington Navy Yard, Washington, DC (N00024-10-D-6618).
The lab does a lot of civilian and military work, and even civilian programs like the Regional Scale Nodes Project ocean observatory would expand ocean access in ways that apply to both civilian and military systems. APL-UW will provide research, development, and engineering to US NAVSEA in 7 core competency areas that NAVSEA has deemed essential to support a variety of specific military programs. While this sort of work is less visible than buying a $700 million Littoral Combat Ship/ frigate, the combined effects of these efforts could be very significant in maintaining the US Navy’s future edge:
- Experimental oceanography
- Acoustic propagation
- Underwater instrumentation and equipment
- Marine corrosion
- Acoustic and related systems
- Simulations and signal processing; and
- Mission related research and development

MH-60S w. AQS-20
Advances made in American mine detection technologies during the mid 2000s included the AQS-20A mine detecting sonar array and airborne laser systems mounted to MH-60S helicopters. All of this is in the service of the USA’s new naval emphasis on littoral warfare and accompanying doctrinal changes. So, what’s the AN/AQS-20? And how is it also related to a new US ship class, not to mention a new undersea robot?

Defense was an issue in the 2007 Australian election. The center-left Labor Party attacked the center-right Liberal Party by citing mismanaged projects, and accusing the Howard government of making poor choices on key defense platforms like the F/A-18F Super Hornet and F-35A Joint Strike fighters. That sniping continued even after Labor won the election, and has been evident in more than a few Defence Ministry releases.
The new government made some program changes, such as canceling the SH-2G Seasprite contract. Yet it has been more notable for the programs it has not changed: problematic upgrades of Australia’s Oliver Hazard Perry frigates were continued, the late purchase of F/A-18F Super Hornets was ratified rather than canceled, and observers waited for the real shoe to drop: the government’s promised 2009 Defence White Paper, which would lay out Australia’s long-term strategic assessments, and procurement plans.
On May 2/09, Australia’s government released “Defending Australia in the Asia Pacific Century: Force 2030.” DID has reviewed that document, and the reaction to date including a new ASPI roundup of reactions from around Asia.
