59 -- SOURCES SOUGHT FOR ELECTRONIC TIME FUZE FOR THE EX172 CARGO ROUND SOL N00178-00-Q-1011 DUE 010500 POC Janice S. Williams, Contract Specialist, Code SD118, (540)653-7478, or Paul Learn, Contracting Officer WEB: NSWCDD Dahlgren Laboratory Procurement Division Web, http://www.nswc.navy.mil/supply. E-MAIL: Contract Specialist for N00178-00-Q-1011, williamsjs@nswc.navy.mil. The Naval Surface Warfare Center, Dahlgren Division (NSWCDD) is seeking information and sources regarding the furnishing of an Electronic Time fuze (ET fuze) for application on the EX 172 Cargo Round. The EX 172 is the Navy's Improved Conventional Munition (ICM) intended for use with the MK 45 gun weapon system. The objective is to acquire a commercial-off-the-shelf (COTS) ET fuze or to develop and qualify a low cost alternative to the MK 429 fuze. The Navy's immediate requirement is for 14,300 ET fuzes by the second quarter of FY 01 for use on the 5-Inch Cargo Projectile (EX 172, HE-ICM). The fuze must meet the system interface requirements as detailed in PERF-SPC-00100 for the MK 429 Fuze. The fuze will be considered as an alternative to the MK 429 fuze and must meet all system interface requirements of the MK 429 fuze as summarized below and detailed in PERF-SPC-00100. Specific requirements are as follows: The fuze shall properly interface with all modifications of the MK45 gun weapon system including the MK86 and MK34 Gun Fire Control Systems (GFCS), the MK34 Inductive Setter, and the MK45, 5"/54 and 5"/62 Caliber Gun Mounts. The fuze contour shall conform to dimensions of MIL-STD-333, Figure 1. The fuze output shall be capable of reliably initiating the expulsion charge in the EX 172 round. The fuze shall accept Time Of Flight (TOF) information from the MK 34 Inductive Fuze Setter in increments of 0.01- second to 135.00 seconds. The accuracy of the ET mode functioning time shall be [30 milliseconds + 0.1% of the programmed TOF]. The setting message in the fuze, prior to gunfire, shall be retained at least 10 minutes. Memory retention shall not exceed 24 hours. The default mode of operation, should the setter message be in error, or loss of power, shall be dud. The fuze design shall conform to the safety requirements of MIL-STD-1316 and the following requirements: a) Arming distance -- The fuze shall not arm after gun firing earlier than 200 feet from the end of the gun muzzle. b) Overhead safety—The probability of unintended fuze functioning beyond the arming distances shall be no greater than one in one thousand, with the goal of no greater than one in one million. c)Insensitive munitions -- The fuze shall not prohibit the EX 172 round from meeting the Navy's Insensitive Munitions requirements. The fuze shall maintain its reliability requirements during its storage and service life. Standard reliability demonstration and analytical techniques shall be applied. The fuze's storage life shall be 20 years in ammunition containers and the fuze's service life is at least ten (10) years. Service life includes, but is not limited to, fuze removal from ammunition container, installation on the projectile and transport to storage depots and ship magazines. The combined storage life and service life is not required to exceed 20 years. The fuze shall require no maintenance and shall be capable of meeting the environmental conditions of MIL-STD-331. Responses to this Sources Sought Announcement shall include a brief description of the fuze indicating whether it is a commercial-off-the-shelf product, a Rough Order of Magnitude (unit) cost estimate, and the estimated production ready date. NO SOLICITATION EXISTS AT THIS TIME. This request is for information only and is intended to identify items currently available or companies capable of providing the fuze identified herein. When responding, please reference Sources Sought Announcement Number N00178-00-Q-1011, provide the company name, point of contact, telephone and facsimile numbers, Internet address, business size, and specific information regarding your capabilities to provide the Electronic Time fuze described herein. THE GOVERNMENT DOES NOT INTEND TO AWARD A CONTRACT ON THE BASIS OF THIS SOURCES SOUGHT ANNOUNCEMENT OR TO OTHERWISE PAY FOR THE INFORMATION REQUESTED HEREIN. Questions regarding this announcement shall be forwarded to Code SD11 at (540) 653-7478 or via Internet at sd11@nswc.navy.mil or via facsimile at (540) 653-7088. Written responses to this announcement shall be received not later than 05 January 2000 and be forwarded to Contracting Officer, Naval Surface Warfare Center, Dahlgren Division, Attn: SD11, N00178-00-Q-1011, 17320 Dahlgren Road, Dahlgren, Virginia 22448-5100.
