Quick Summary
The Naval Sea Systems Command (NAVSEA) intends to award a sole-source contract modification to Leidos Holdings, Inc. for Acoustic Device Countermeasure (ADC) MK 5 Low-Rate Initial Production (LRIP) units and associated engineering support. This action is being pursued under other than full and open competition due to Leidos being the original developer and the Government's current lack of a complete Technical Data Package (TDP). This is critical to meet fleet deployment and testing schedules without unacceptable delays. Interested parties may submit capability statements by May 8, 2026.
Scope of Work
This modification will procure additional LRIP units and engineering support for the ADC MK 5, an expendable, mobile acoustic countermeasure designed to enhance submarine survivability against torpedo threats. The work is necessary while the TDP is finalized for future full and open competition.
