Douglas Caster, chief executive of Ultra, said: "This important contract emphasises the superiority of Ultra's innovative HiPPAG technology to meet this key requirement.
"HiPPAG is demonstrating impressive reliability and a low cost of ownership, not just for missile cooling but also in providing the energy source for advanced weapons ejection systems on the US Small Diameter Bomb and F-35 Joint Strike Fighter programmes.
Recently Ultra Electronics announced that the Precision Air Systems business had won a deal to supply Hippag
for Boeing's X-45 unmanned combat air vehicle programme.
HiPPAG 320 is a miniature, electronically controlled compressor and filtration system, designed as an onboard source of pure air for cooling infra-red seekers of an aircraft's airto-air missiles.
Ultra has been advised by the US Navy that the HiPPAG system 'significantly enhanced combat readinessand deployability' of the F/A-18 aircraft during recent military operations in Afghanistan and Iraq.'
HiPPAG is also in service on the Italian Navy Harrier II Plus and the Royal Air Force of Oman's Hawks and Jaguars and is in production for Eurofighter.
Dr Frank Hope, managing director of Ultra's aircraft & vehicle systems division, said: 'This further contract from the US Navy emphasises the superiority of Ultra's innovative HiPPAG technology.
'In its missile cooling role, HiPPAG has an unbeatable track record of proven savings in logistics support costs.
The order, received from EDO Corporation, is for the qualifica- tion of Ultra's HiPPAG 520 air- borne compressor and its inte- gration into the weapons bay and pylons of the advanced new aircraft.
The HiPPAG 500 technology is derived from the highly success- ful HiPPAG 320 - over 1,200 are in service - cooling seekers on short-range air-to-air missiles on US Navy and Marine aircraft.
The HiPPAG system has been in operational service on US Marine Corps Harrier and Super Cobra aircraft since 1977.
