The Naval Sea Systems Command (NAVSEA) is seeking sources to develop and produce a Large Vertical Array (LVA) for SONAR. The LVA will be used on Ohio Class and Virginia Class submarines. Interested parties should provide a capability statement addressing their experience and expertise in developing and producing large submarine hull-mounted arrays. The statement should include information on sensor and array performance, technical approach, and maintainability. Respondents should also provide a rough order of magnitude cost estimate and describe any barriers to competition. Some key requirements for the LVA include: • The ability to produce large submarine hull-mounted arrays • The capability to sustain a throughput of up to two LVA systems per year • The use of materials that can withstand years-long periods of submersion in salt water and harsh environments • The ability to integrate and interoperate with the AN/BQQ-10(V) Sonar System • Compliance with performance specifications and requirements for outboard electronics and acoustic panels.
