The Department of Defense, through the NAVSUP Weapon Systems Support office, is planning to issue a sole source solicitation for a Bifilar Assembly (NSN: 1615 012212610, P/N: 70107-28400-043) specifically designed for the H60 platform, with Sikorsky identified as the only known source for this part. This procurement is critical as the government lacks the necessary data and rights to procure the assembly from alternative manufacturers, emphasizing the importance of maintaining established supply chains for military support. The solicitation is expected to be issued in March 2025, with a closing date later that month and an anticipated award date in July 2025; interested suppliers are encouraged to submit capability statements within 15 days and can contact Samantha M. Freedman at samantha.m.freedman.civ@us.navy.mil for further inquiries.
