Navy upgrading sea-mine sweeper helicopters: budget cuts could slow development of airborne mine countermeasures.
The U.S. Navy intends to deploy the first MH-60S Knighthawk helicopters equipped with organic airborne mine countermeasures All methods for preventing or reducing damage or danger from mines. Also called MCM. with carrier battle groups in 2005.
Although the service has not yet designated which carriers will receive the countermine equipment, planners expect forward-deployed helicopter sea combat squadrons with Sikorsky Knighthawks to replace dedicated helicopter mine countermeasures squadrons flying the MH-53E Sea Dragon Sea´ drag´on

"The beauty of the organic construct is that they're already in theater," observes Capt. James Rennie, the mine warfare The strategic, operational, and tactical use of mines and mine countermeasures.

Seven new organic mine countermeasure programs are in development, five of which are helicopter based.
Helicopters have swept mines since the mid-1960s. The Sikorsky M-53Es can be airlifted on Air Force C-5 jet transports or self-deployed with aerial refueling.
In February, HM-15 filled six C-5s to deploy four Sea Dragons, 135 people and 200 tons of equipment to Bahrain in support of Operation Iraqi Freedom. The helicopters used side-looking sonar, noisemakers and magnetic sleds to sweep the shallow Khor Abd Allah waterway feeding the key Iraqi port of Umm Qasr.
Four more MH-53Es deployed soon afterwards to Sicily to provide countermine capability around the Suez Canal. The heavy-lift helicopters also serve as cargo carriers.
Once in-theater, Sea Dragons operate from shore bases, mine warfare command ships or amphibious ships. The three-engine MH-53E can tow the 8,000-pound Mk 105 magnetic/acoustic minesweeping sled through high seas high seas

The 70,000-pound helicopter sustains 25,000-pound tow tension and absorbs surges near 40,000 pounds in high sea states.

The 23,000-pound Knighthawk blends the utility airframe of the Army Black Hawk with the maritime features of the Navy Seahawk and shares a common cockpit with the Navy's multi-sensor MH-60R. Sikorsky Aircraft delivered the first production MH-60S configured for mine countermeasures in August 2003. The mine-sweeping Knighthawk incorporates a tow point in the lower fuselage, hookups for a mine countermeasures operator console, and a 400-gallon auxiliary internal fuel tank.

v. and other missions from ships at sea. The 51st production MH-60S and all subsequent Knighthawks will be adapted for mine countermeasure kits. "We're now planning to buy 44 kits," says Rennie. "That is probably going to be the lowest number." Each kit will ultimately include five new organic minesweeping systems.

Under a 2001 contract, Lockheed Martin is integrating Block A mine countermeasure systems into the MH-60S aircraft.
The mine countermeasures console interfaces with sensors and with the GPS-assisted inertial navigator in the helicopter. It has a single large display that shows multiple views for each sensor and a smaller navigation display identical to those in the Knighthawk cockpit. According to Lockheed Martin director of multi-mission helicopter programs, Paul Monseur, "It's one console for all sensors, one common look and feel for all of them."

Block A systems operational on the Knighthawk in 2005 include the Raytheon AN/AQS-20 mine-hunting sonar and the Northrop Grumman Airborne Laser Mine Detection System (ALMDS ALMDS Airborne Laser Mine Detection System ).
The towed AQS-20 fish uses multiple sonars to scan large volumes of ocean quickly, and has an electro-optical imaging capability to detect and classify mines in one pass. ALMDS uses an aircraft-mounted LIDAR (light detection and ranging) sensor to detect floating mines and moored mines down to the keel depth of ships.
The common cockpit displays of the MH-60S and MH-60R remain unchanged, but additional software gives minesweeping crews tow tension and skew (1) The misalignment of a document or punch card in the feed tray or hopper that prohibits it from being scanned or read properly.

There are concerns, however, about future funding fur ALMDS. This fiscal year, Congress cut $11.4 million from the program. That will prevent the Navy from starting low-rate production, unless it can reprogram re·pro·gram

re money, possibly from other mine countermeasure programs, said a Navy source. ALMDS was scheduled to go through Milestone C in January 2004.
If the funds are not restored, Northrop Grumman would continue development work, but would not produce any systems, said a company official.
Lockheed Martin received a contract in September 2003 to develop organic mine countermeasure systems on the MH-60S. The Block B capability in 2007 introduces the AN/AQS-232 AMNS AMNS Airborne Mine Neutralization System

adj. mine-neutralization system, the AMNS enables the MH-60S to relocate, identify and neutralize mines previously found by AQS-20 sonar, the ALMDS laser detector or other mine warfare platforms. The hovering helicopter deploys an expendable, stir-propelled neutralizer steered to the suspected mine by the MH-60S operator. Sonar and video displays on the airborne console help identify a potential mine threat. Confirmed mines are destroyed or detonated with a shaped charge.
The RAMICS uses a laser-aimed 30 mm Bushmaster II cannon to neutralize near-surface, floating and shallow-bottom mines. The blue-green laser penetrates the water to target the mine for the stabilized, rapid-fire gun.

The OASIS combines the acoustic and magnetic mine detonation functions now performed by noisemakers and magnetic sleds in a single towed body. Deployed from the helicopter, it emulates ship signatures in shallow water at speeds up to 40 knots.
The Navy's helicopter master plan introduced the MH-60S (originally CH-60S) Knighthawk to replace the CH-46 Sea Knight The Boeing CH-46 Sea Knight is a medium-lift tandem rotor assault helicopter, used by the United States Marine Corps (USMC) to provide all-weather, day-or-night assault transport of combat troops, supplies and equipment. , UH-3H Sea King and HH-60H Seahawk in a variety of roles. The MH-60S completed its first operational deployment with squadron HC-5 last May. The 14-helicopter squadron kept two aircraft at Guam and deployed six two aircraft detachments aboard ships at sea.
Current helicopter combat squadrons will be redesignated HSC HSC - High Speed Connect when the Navy implements its helicopter consolidated operations plans in 2005. The goal is to have MH-60Ss equipped for airborne mine countermeasures on any aviation-capable ship. In carrier strike groups, the helicopters come from carrier-based MH-60S squadrons. In expeditionary strike groups, smaller ships will support HSC expeditionary detachments.
Notional plans call for four mine countermeasures-equipped helicopters in the expeditionary strike force. Each two-aircraft detachment has 26 people. HSC crews will train for mine warfare along with combat rescue and other missions. "The way we see it, every aircrew will have that skill," says Wheeler.
Countermine missions nevertheless will make additional demands on HSC crews. Today's dedicated mine-warfare squadrons emphasize crew coordination and specialized pilot training. Air taxiing through sliding turns low above the water with minesweeping gear in tow takes practice.
More responsive, less-costly organic systems put additional demands on the MH-60S helicopter. Towing minesweeping gear inevitably takes a toll on aircraft. Mine countermeasures add about 300 pounds to the empty weight of the MH-60S, compromising performance in cargo and other roles. Sikorsky is studying weight reduction options, including composite stabilizers and lightweight crew seats.
With around 6,000 pounds sustained and 9,000 pounds peak tow tension and a comparatively small cabin, the MH-60S cannot use the Mk 105 sled or Mk 103 cutter array deployed with the MH-53E.

"It's our intent to deploy a capability equal to or greater than the -53 capability," says Rennie.
RELATED ARTICLE: Advanced technology demonstrations proven in Iraq.
The war in Iraq helped demonstrate several Defense Department research and development programs that started out more than a decade ago as Advanced Concept Technology Demonstrations.
ACTDs were designed to identify and demonstrate the military utility of technologies aimed at solving problems documented by regional combatant commanders. If successful, ACTDs help to expedite the process of providing these technologies to the front lines.
A case in point is the Joint Precision Strike Demonstration (JPSD JPSD Joint Precision Strike Demonstration
JPSD Joint Programs Sustainment and Development (Army project office) ) project office, established in 1992. Based on lessons learned from Operation Desert Storm Noun 1. Operation Desert Storm - the United States and its allies defeated Iraq in a ground war that lasted 100 hours (1991)

Leading this effort is the Army program executive office for intelligence, electronic warfare and sensors (PEO IEW&S).
For nearly a decade, the JPSD has sought to identify and develop ACTDs to improve sensor-to-shooter precision strike processes, a mission that continues today. JPSD has since expanded into other relevant technology areas such as terrain visualization, urban reconnaissance, unmanned aerial vehicles
JPSD contributions to Operation Iraqi Freedom included command and control systems for U.S. forces, supporting intelligence decision makers throughout the conflict JPSD has averaged 50 deployed PEO IEW&S personnel in Iraq since fall 2002. The organization continues to maintain a significant presence in theater, providing assistance to reconstruction and humanitarian effort.
Two other ACTDs that contributed to the operations in Iraq are the Theater Precision Strike Operations (TPSO TPSO Theater Precision Strike Operations (ACTD) ) and Joint Intelligence Surveillance Reconnaissance (JISR JISR Joint Intelligence, Surveillance and Reconnaissance ) systems.
TPSO is based on the Automated Deep Operations Coordination System (ADOCS ADOCS Automated Deep Operations Coordination System (US DoD)
ADOCS Advanced Digital Optical Control System (US Army)
ADOCS Air Defense Operations Center System ), which provides interfaces to facilitate coordination between multi-service targeting systems and mission software tools. During the combat phase of Operation Iraqi Freedom, approximately 1,200 applications were installed in Central Command's joint and component headquarters.
The JISR technology is being used in Iraq to help improve the quality of battlefield intelligence. JISR is a Web-based application that lets commanders see the location of blue and red forces. It operates on the SIPRNET classified network.
Although not an ACTD, the Central Command deployable headquarters project is an example how the Joint Precision Strike Demonstration can respond to war-fighter requirements.
Within 10 months of receiving the tasking, JPSD delivered the CDHQ CDHQ CD (Compact Disc) Headquarters (music membership club; BMG Music Club) system to, presently deployed in Qatar, to support the commander and his staff. CDHQ supports real-time strategic situational awareness and provided a platform for Central Command to plan the campaign.
In March 2003, the JPSD project office was asked by the Office of Coalition and Provisional Authority (OCPA OCPA Oklahoma Council of Public Affairs
OCPA Office of the Commissioner for Public Appointments (UK)

The OCPA headquarters consists of network servers and robust communication capabilities that include telephone infrastructure for 250 people, commercial satellite connectivity and audiovisual resources. The three first-responder vehicles will be used as incident management and civil responder assets for OCPA, envisioned to operate in the north, south and center of Iraq.
JPSD will continue to support Defense Department requirements and the ACTD process. Future strategic plans include work in the areas of intelligence and sensor fusion, dynamic sensor management, effects based operations and modeling and simulation support to Army and joint programs.
