C2 Greyhound transport aircraft

The US Navy has recently begun to attack the C-2 Transport aircraft Make improvements, change outfits General Electric Company CF-34-3B Turbofan engine . Comprehensive fatigue testing of the C-2 aircraft has been completed to determine where life extension modifications are required. After the life extension the aircraft will be from the current 10000 Flight hour And 15,000 takeoffs and landings increased to 15,000 flight hours and 36,000 takeoffs and landings at a cost of about $45 million per aircraft. After the modification, the aircraft was called" supercarrier Transport aircraft ", will replace C-2 transport aircraft , S-3 Refueling machine And the E-2 aircraft. According to the calculation, the cost of retrofit 36 C-2 aircraft is only $1.5 billion, while the development of the next generation of CSA general support aircraft will cost at least $5 billion.
