HH-60Gs have folding rotor blades. Pave Hawk combat enhancements include a radar warning receiver, infrared jammer and a flare/chaff countermeasure dispensing system. HH-60G rescue equipment includes a hoist capable of lifting a 600-pound (270 kg) load from a hover height of 200 feet (60 m), and a personnel locating system. A number of Pave Hawks are equipped with an over-the-horizon tactical data receiver that is capable of receiving near real-time mission update information. Replacement helicopter In 1999, the USAF identified a need for a helicopter with improved range, speed, and cabin space. An options analysis was completed in 2002 and funding for 141 aircraft under the "personnel recovery vehicle" program began in 2004. In 2005, it was renamed CSAR-X, meaning combat search and rescue. Sikorsky entered the HH-92 Superhawk, Lockheed Martin entered the VH-71 Kestrel, and Boeing entered the HH-47 Chinook. The HH-47 won the competition in November 2006, but the award was cancelled after successful protests from both rival competitors. A Request for Proposals (RFP) was reissued in 2007, but protested again before proposals were received, leading to a second cancellation. In March 2010, the USAF announced a recapitalization plan to return its 99-aircraft inventory to 112 airframes, incrementally replacing aging HH-60Gs; a secondary plan to replace 13 attrition HH-60s, seven of which were lost in combat since 2001, was also initiated. The USAF deferred secondary combat search and rescue requirements calling for a larger helicopter. A UH-60M-based version was offered as a replacement. On 22 October 2012, the USAF issued an RFP for up to 112 Combat Rescue Helicopters (CRH) to replace the HH-60G with the primary mission of personnel recovery from hostile territory; other missions include civil search and rescue, disaster relief, casualty and medical evacuation. It had to have a combat radius of , a payload of 1,500 lb (680 kg), and space for up to four stretchers. The AgustaWestland AW101 was one entrant. By December 2012, competitors AgustaWestland, EADS, Boeing, and Bell Helicopter had withdrawn amid claims that the RFP favored Sikorsky and did not reward rival aircraft's capabilities. The USAF argued that the competition was not written to favor Sikorsky, and that the terms were clear as to the capabilities they wanted and could afford. Sikorsky was the only bidder remaining, with subcontractor Lockheed Martin supplying mission equipment and the electronic survivability suite. Sikorsky and the USAF extensively evaluated the proposed CRH-60, a variant
