Evolved SEASPARROW Missile (ESSM) Releasable Seeker Assembly Sources Sought

Background/Program Details:

The NATO SEASPARROW Project Office (NSPO), PEO IWS 12.0, is seeking concepts for a seeker subsystem for their Next Significant Variant (NSV) of the ESSM missile. The seeker assembly must be fully releasable to all 12 Nations and be designed to enable long-term affordability, rapid capability insertion, and international cooperation.

To meet these goals, NSPO expects the seeker design to follow an open, modular, and standards-driven architecture and to incorporate open-source principles and deliverables wherever feasible. This approach will simplify future upgrades, promote interoperability across consortium platforms, and outpace evolving threats.

The NSPO is the program office responsible for the Evolved Seasparrow family of missiles.

NSPO is a twelve-nation consortium (Australia, Belgium, Canada, Denmark, Germany, Greece, Netherlands, Norway, Portugal, Spain, Türkiye, United States) with a mission to provide a platform for international cooperation and innovation to manage the development, production, integration, and sustainment of effective, reliable, and affordable weapon systems to protect consortium and partner nation forces from current and future threats. More information on the NATO SEASPARROW Surface

Missile System Project can be found at this link; https://www.natoseasparrow.org/.

The pace by which adversary’s weapons systems evolve challenges the consortium test community’s development and acquisition cycle timelines. Therefore, to reduce the number of acquisition cycles, a modern, open, flexible, and modular seeker is vital for NSPO to outpace our adversaries.

This RFI is seeking concept descriptions for a missile seeker assembly design that satisfies the operational needs described below. Figure 1 is an example of the operational view for the missile system.

Figure 1: Distribution Statement A. approved for public release: distribution is unlimited. Example Operational View https://www.natoseasparrow.org/

Requirements for Seeker Assembly

The future seeker assembly should have capability against current and future threat classes spanning a variety of threat characteristics including velocity (low-speed to high-speed), altitude (sea skimming to high diver), maneuverability (non-maneuvering to high G weaves) and signatures. The seeker should be able to work in complex natural, RF and/or IR environments.

The seeker should have capability to perform target search & acquisition processing using cueing information provided by an external source. It should have the capability to track multiple targets within its field of regard. The seeker should have the capability to discriminate and resolve between multiple targets and to provide threat track measurements to support missile guidance, navigation and fuzing functions. The seeker should have the capability to handle threat countermeasures.

The proposed seeker system must be able to integrate with a 10” diameter missile body to maintain

Mk 41 quad-pack compatibility. The seeker subsystem must be integrated into the missile guidance section. Design considerations should be made to minimize size, weight and power consumption of the seeker subsystem

The seeker should be releasable to entire ESSM Consortium (Australia, Belgium, Canada, Denmark, Germany, Greece, Netherlands, Norway, Portugal, Spain, Türkiye, and the United States.)

To support the NSV, NSPO intends the seeker design and supporting software/firmware to follow an open-source architecture approach. The Government is seeking responses that describe architectures and deliverables that: provide the Government maximum rights in technical data, computer software, and computer software documentation (including source code), design artifacts, and interface specifications under a license consistent with at least Government Purpose Rights under the DFARS, or a similar deliverable model. The Government anticipates that any future solicitation and/or source selection will emphasize data rights licenses pursuant to the Defense Federal Acquisition Regulation

Supplement (DFARS).
