The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking contractors to repair two units of HEAT EXCHANGER for the country of Taiwan. The procurement involves providing labor, materials, and facilities necessary to restore the specified items to operational condition, particularly focusing on the HEAT EXCHANGER with part number 123SCEC5150-5 and NSN 7R1660012539510, which is utilized in the E-2 aircraft. The government intends to solicit only one source, NORTHROP GRUMMAN, under FAR 6.302-1, due to the lack of available data for repairs; however, all responsible sources may submit capability statements within five days of the notice. Interested parties should contact Liem Phan at 215-697-5722 or via email at liem.m.phan.civ@us.navy.mil for further information.
