Defence Equipment & Support (DE&S), as the procurement arm of the Ministry of Defence (MoD), is engaged in procurement activity for Project SERPENS, a digitally integrated weapon locating system, to be employed as counterbattery assets comprising artillery weapon locating sensors and radars which will be installed onto in-service land vehicles and integrated with communications bearer networks. The planned out-of-service date (OSD) for the SERPENS system is 2057. SERPENS plans to procure a quantity of twenty-five (25) Close Find Radars using a competitive flexible procedure (s.20) under a staged delivery schedule to complete during calendar year 2027. Focus is on high technological readiness with priority on key requirements following which development will focus on the mounting of radar assets onto vehicles, integration with inservice comms bearer/s and, in future, integration into SERPENS as a networked array of sensors. The planned core term for this contracting opportunity will be six (6) years, estimating equipment deliveries within no more than two (2) years followed by four (4) years of in-service support. Options are planned to be implemented to extend the in-service support beyond the core six-year term as a de-risking measure based on the complexity of system integration requirements for the SERPENS system. SERPENS reserves the right to procure additional CFR systems during the performance period of any resultant contract, for the purposes of counter rocket, artillery and mortar (C-RAM), or counter unmanned aerial surveillance (C-UAS), or any other air defence or surveillance roles. The in-service support provisions of any contract awarded may be extended to provide the same, or similar, support services towards any additional systems procured under the performance of the contract. For the avoidance of doubt, a permitted modification/direct award may be made in the event that additional goods and/or services are to be procured for the same or similar use cases by the Armed Forces. Should any company be interested in expressing interest for this contracting opportunity, and you have not previously engaged with the SERPENS team, please contact the associated buyer who will be able to provide registration details for the SERPENS AWARD portal.
