10 -- WEAPONS SOL N00024-99-R-5468 DUE 041299 POC (02544F), P. Franzel, (703)602-8000 The sources sought announcement regarding solicitation N00024-99-R-5468 as it appeared in CBD Issue 2/22/1999 is amended to provide a more detailed description of "Nulka" MK 53 Decoy Launching System (DLS) Modification Kits. The MK 53 DLS is a deck mounted, mortar type, countermeasure system that is used to launch a variety of decoy cartridges associated with Antiship Missiles (ASMs). The main focus of the MK 53 is to launch the MK 234 Electronic Decoy Cartridge (EDC). The major components of the MK 53 DLS are: Decoy Launch Processor; Bridge Launcher Control units; Processor Power Supply units; MK 137 Launchers; and MK 5 MOD 4 Ready Service Lockers. The MK 53 DLS Modification Kit consists of: the newly designed Decoy Launch Processor (DLP), MK 24 MOD 2; Processor Power Supply (PPS); and the Decoy Launcher Modification Kit. The DLP MK 24 MOD 2 consists of the hardware and software necessary for proper decoy selection and programming in response to inputs from the AN/SLQ-32A(V) Display and Control Console (DCC). The DLP accepts threat data, threat bearing, and firing commands from the AN/SLQ-32A(V) DCC via a direct RS-232-D interface. Ship environmental, motion and speed data are provided to the DLP via multiple synchro channels direct from the ship's Interior Communications (IC) switchboard. The DLP selects the proper decoy and generates messages to the specific Processor Power Supply (PPS) in order to initiate decoy launch. The DLP also develops and provides commands to fly a trajectory optimized for the threat and provides monitoring and control of the MK 53 DLS and decoy engagement status to the AN/SLQ-32A(V) EWS. Electrical power requirements are 115 VAC RMS, 3.5 amps, single phase 60 hertz 10 hertz ships service power. The PPS provides the electrical and data interface between the DLP and the launcher, and power to initiate decoy launch. There is a PPS associated with each launcher. The PPS is located below deck in the vicinity (within 60 feet) of the launcher. Interface with the DLP is via multiple RS422 channels, and analog lines. Electrical power requirements for each PPS are 115 VAC RMS, 11 amps, single phase 60 hertz 10 hertz ships service power. There are six PPS per ship. [All six of the current power supplies will be replaced.] The Decoy Launcher Modification kit consists of a dual canister configuration for launching MK 234 EDC (four of the six MK137s launchers will be modified). The approximate size of this decoy launch canister is 12"x24"x94" plus supporting hardware. During installation of the system, this kit will be mounted piggyback onto an existing MK 137 Launcher or will be mounted on a MK 137 Launcher foundation as a standalone Launcher. Electrical power requirement is 28 VDC, supplied through the PPS. The Standard Industrial Classification (SIC) for the MK 53 DLS modification kits is 3769, which has an industry employment size standard of 1000 employees. Any interested contractor must possess a SECRET facility clearance and a SECRET capability or be eligible for a clearance. No solicitation package is available at this time. Submissions of interest must specify the size of the Contractor's business concern and provide detailed information on the Contractor's capabilities and experience in the production of the same or products of similar complexity. Written responses must be received on or before 12 April 1999, directed to the attention of Pam Franzel/SEA 02544F at Naval Sea Systems Command, 2531 Jefferson Davis Highway, Arlington, VA 22242-5160; telephone (703) 602-8000 x561; fax (703) 602-4770; e-mail, franzel_pamela@hq.navsea.navy.mil. Responses to the sources sought announcement regarding solicitation N00024-99-R-5468 as it appeared in CBD Issue 2/22/1999 will be disregarded; all interested sources must respond to this amended synopsis.
