NAVSUP Submarine Mechanical-Electronics Systems 2015-2017

Naval Sea Systems Command established this Master IDIQ on July 23, 2015, to provide submarine mechanical, electrical, and electronics engineering, analytical, logistics, and technical support services to the Mid Atlantic Regional Maintenance Center. Ordering closed on July 22, 2019—the vehicle is no longer active and has been closed for nearly seven years.

Sixty-one task orders were awarded under the vehicle between March 2016 and July 2019, with ordering momentum declining sharply in the final two years (25 orders in 2016, 18 in 2017, 11 in 2018, and 7 in 2019). Combined potential value across all task orders is $83.6 million, with $70.5 million obligated (84% of the ceiling).

The three prime contractors awarded reflect a highly concentrated structure. Amentum Services, Inc. holds 36 orders valued at $54 million combined potential—roughly 65% of the vehicle's total work. L3Harris Maritime Services Inc. ranks second with 18 orders and $22.5 million (27%), while HII Mission Technologies Corp. holds the remaining 7 orders and $7.2 million (9%). The customer base shows no diversification: Naval Sea Systems Command placed 60 of the 61 orders, representing $83.3 million in combined potential value, with a single order to United States Fleet Forces Command (Atlantic) for $303 thousand.

All 61 task orders carry unrestricted (non-set-aside) designations. Pricing splits between Cost-Plus-Fixed-Fee (CPFF) and Firm-Fixed-Price (FFP) arrangements, with individual task-order ceilings ranging from under $100 thousand to roughly $7.5 million. Representative work includes submarine hull, mechanical, and electrical support; combat systems and acoustic systems technical services; submarine local area network (SUBLAN) systems support; and peculiar support equipment (PSSE) maintenance. Task orders fund efforts at multiple Navy locations, including the Mid Atlantic Regional Maintenance Center (Groton, Connecticut), naval submarine support facilities, and fleet commands.

This vehicle is closed to new orders. Existing task-order awardees may still perform under existing obligations, but the vehicle presents no pursuit opportunity for new primes.

This Master IDIQ is to provide Submarine Mechanical and Electrical engineering, analytical, logistics, and technical support services to the Mid Atlantic Regional Maintenance Center (MARMC).
