Solicitation # N0038326QNB29

This contract is for the procurement of 17 units of a flight critical display processor under NSN 7R-7010-015222097-LC, with delivery terms set as FOB Origin. Due to the critical nature of the part and the fact that essential technical data and manufacturing knowledge are held by specific sources, the government requires engineering source approval from the design control activity to ensure quality. The government intends to negotiate with a single source under FAR 6.302-1, though other responsible sources may submit capability statements or proposals within the specified timeframe for consideration. Prospective bidders who are not already approved sources must submit detailed information as outlined in the NAVSUP Weapon Systems Support Source Approval Information Brochures. Failure to provide the required data or proof of a pending approval request will result in the proposal not being considered for award. The government maintains the discretion to proceed with a non-competitive award based on fleet support needs if new source approvals cannot be processed in time to meet operational requirements.

Solicitation # N0016426SNC05

The Naval Surface Warfare Center, Crane, is seeking a two-year ordering period extension and ceiling increase for contract N0016426DGP87 to procure TR-143A Transducers, part number 7146100-302. These specialized components are critical to the SP24 Trident Navigation Subsystem, which supports the launch accuracy of U.S. Ohio and Columbia class submarines as well as UK Vanguard and Dreadnought class submarines.

AI Contract Overview

The Naval Sea Systems Command plans to modify an existing contract with Leidos Holdings, Inc. under N00024-18-C-6209 to procure additional Low-Rate Initial Production units and engineering support for the Acoustic Device Countermeasure (ADC) MK 5, an expendable mobile system designed to enhance submarine survivability against torpedo threats.

Full Description

The Naval Sea Systems Command (NAVSEA) intends to award a contract modification to Leidos Holdings, Inc. under Contract No. N00024-18-C-6209. The modification will be issued using other than full and open competition pursuant to 10 U.S.C. § 3204(a)(1), as implemented by Federal Acquisition Regulation (FAR) 6.302-1.

The Acoustic Device Countermeasure (ADC) MK 5 is an expendable, mobile acoustic countermeasure designed to increase a submarine’s survivability against torpedo threats. Leidos is the original developer of the ADC MK 5 system, and the Government does not currently possess a complete Technical Data Package (TDP) with build-to-print specifications. This action is required to procure additional Low-Rate Initial Production (LRIP) units and associated engineering support to meet critical fleet deployment and testing schedules. Leidos is determined to be the only available source capable of fulfilling these requirements without causing unacceptable schedule delays while the TDP is finalized for future full and open competition.

Interested parties may express their interest and capability in response to this notice. Parties may submit a capability statement detailing their technical expertise and ability to fulfill the requirements, which will be considered by NAVSEA. Responses shall be submitted via email to christopher.t.venturino.civ@us.navy.mil and cc jennifer.l.kramer26civ@us.navy.mil and reference the solicitation number.
