Latest updates[?]: Archerfish (AMNS) order.
Old school:
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.

ROKAF F-15K
In late November 2011, South Korea’s left-wing Hankyoreh newspaper reports that a combination of unauthorized examination of an F-15K’s Lockheed Martin “Tiger Eyes” IRST(InfraRed Search and Track) sensor, and concerns that a number of South Korean products contain copied technologies, have halted “strategic weapons exports” from the USA to South Korea. That reportedly includes the proposed RQ-4B Global Hawk deal.
The allegations are single-source, and written by Hankyoreh, but they are also quite detailed:

VL-ASROC test
Lockheed Martin Corp. in Akron, OH received a $16.7 million undefinitized ceiling priced order under a previously awarded contract, to build various components for the MK54 vertical launched ASROC (anti-submarine rocket) missiles. Work will be performed in Akron, OH, and is expected to be complete by August 2012. This contract was not competitively awarded by the US Naval Inventory Control Point in Mechanicsburg, PA (N00104-07-G-0726, #0006). See also FBO solicitation.
The Mk-54 is the USA’s newest lightweight torpedo, replacing the older Mk-46. The RUM-139 VL-ASROC can be crudely described as a rocket attached to a break-away torpedo, which offers a number of advantages. One is an expanded firing range of up to 15 nautical miles or so. Another is the ability to load VL-ASROCs into Mk.41 vertical launch systems. A loaded cell can give even ships without deck-mounted torpedo tubes a snap-response capability against enemy submarines.

Dolphin with mine marker

Just as the dog’s keen sense of smell makes it well suited to detect land mines, so the US Navy has found that the biological sonar of dolphins, called echolocation, makes them effective at locating and marking sea mines.
To take advantage of these skills, the Navy Marine Mammal Program studies, trains, and deploys dolphins, as well as sea lions, to carry out various underwater tasks for the Navy.
As part of the program, the Fleet’s Marine Mammal Systems (MMS) use dolphins and sea lions to find and mark the location of underwater objects…

STS International in Berkeley Springs, WV won a $23.3 million cost-plus-fixed-fee contract for operational capabilities for the surface and subsurface surveillance system (Quad-S). Quad S is a multifunction surveillance system that can be used in both military expeditionary operations and homeland security missions.
STS will perform the work in Tampa, FL and expects to complete it by September 2014. This contract was competitively procured via Navy Electronic Commerce Online and FedBizOpps websites, with 3 proposals received by the Naval Surface Warfare Center (NAVSEA) Panama City Division in Florida (N61331-09-C-0020).
Quad-S integrates a range of maritime sensors…

Alion Science and Technology in McLean, VA received a task order (N00178-04-D-4066) from the US Navy valued at $48.5 million to research, design, develop, prototype, integrate and test a new torpedo detection system in conjunction with the Navy’s anti-torpedo countermeasure technology effort.
The task order, awarded under the Naval Undersea Warfare Center Division Newport’s Seaport-Enhanced (Seaport-e) contract, supports the Naval Sea Systems (NAVSEA) Undersea Defensive Warfare Systems Program Office with anti-torpedo torpedo defensive system (ATTDS) torpedo detection, classification and localization (TDCL) technology.
Seaport-e is a $5.3 billion multiple-award umbrella contract that lets the US Navy use an integrated approach to contracting for support services.
The ATTDS TDCL is a project [PDF] within the Navy’s Surface Ship Torpedo Defense (SSTD) program.
