The Naval Surface Warfare Center Carderock Division (NSWCCD), under the Department of the Navy Naval Sea Systems Command, is seeking contractor support to provide scientific and technical services in underwater explosions (UNDEX) and air explosions (AIREX) analysis of undersea and surface vessels utilizing specialized software codes. The requirement encompasses expertise in shock environment simulation, platform response analysis, computational model validation, finite element modeling, nuclear underwater shock simulation, and ship survivability analysis directed toward research, development, test, and evaluation (RDT&E) for submarine and surface ship programs. Contractors must demonstrate proven experience in UNDEX shock qualification, UNDEX damage assessment, AIREX damage assessment, and related technical fields, with personnel required to possess IAT Level II cybersecurity certifications. The government will evaluate responses to assess both small and large business capabilities to inform small business set-aside determinations under FAR Part 19. Critical deadlines include April 6, 2026 at 1200 ET for submission of questions regarding the notice, April 14, 2026 at 1400 ET for government responses to be posted on SAM.gov, and April 21, 2026 at 1200 ET for submission of completed Market Research Questionnaires and capability statements to the designated points of contact.

This opportunity carries no small business set-aside designation and represents a follow-up to a Sources Sought Notice originally published on April 16, 2025. Current services are performed by three contractors: T. Carroll Associates, Inc. under contract N00167-20-D-0014, The Survice Engineering Company LLC under contract N000167-18-D-0003, and Thornton Tomasetti, Inc. under SeaPort Task Order N0016721F3014. The anticipated contract will be structured as a single-award Cost-Plus-Fixed-Fee (CPFF) arrangement with a potential period of performance of five years (base year plus four one-year option years), with the primary place of performance at the contractor's facilities. The work falls under NAICS code 541330 (Engineering Services) with a small business size standard of $47 million in annual receipts. While specific award values are not disclosed in the pre-solicitation notice, interested parties previously responding to the initial Sources Sought Notice need only reaffirm their interest by email unless their submitted documents have changed materially.
