10 -- CLOSE-IN GUN SUPPORT DUE 092598 POC Timothy Starker, SEA 02523T, (703) 602-7904 x526 The Naval Sea Systems Command invites interested parties to provide information concerning existing development efforts for a weapon system capable of defeating small, fast, highly maneuverable surface craft. The threat is ten (10) radially inbound small craft traveling at 40 knots over calm seas which have survived the outer layer of defense and are to be prevented from closing to within 1000 yds of the ship. The threat can occur during either day or night. The 10 craft are distributed inside a 90-degree arc and a 300-yard range band. The baseline target is a "cigarette boat" which is 12m long, has a 2.6m beam and a 0.9m draft and/or a jetski approximately 3m long. This weapon system may be installed on any surface ship including Coastal Patrol craft, Coast Guard cutters, Destroyers, Cruisers and Amphibious Warfare Ships. The desired weapon system is characterized as follows: BASELINE CONFIGURATION Two axis stabilized (minimum). Remotely controlled, with man-on-the-mount capability desirable. Not integrated into the ships combat system. Does not penetrate the deck (except for power and control cables). Operates from ship's AC power with backup power capable of completing engagement against the threat. Working circle of less than 20 ft (6 meters) in diameter and less than 8 ft (2.4 meters) in height. Capable of being fired by one person and maintained/loaded by 2 personnel. Includes an electro-optical sight for day/night operation, and capability to provide range and ballistic computations and corrections. Operates in Sea State 3 and survives Sea State 5. VARIANTS In addition to the baseline configuration, the weapon system is to be capable of being configured as follows: VARIANT 1: Automatic and continuous tracking of targets after acquisition. VARIANT 2: Integrated with the ships combat system. Companies are requested to provide the following additional information: 1) Provide a description of the system including intended utilization and concept of operations. With the system description, include system size and weight, a description of system development status; i.e., fielded system-in production, Low Rate Initial Production (LRIP) model, or Engineering Development model, etc. If fielded, provide the number of systems fielded and by which service/countries. Also, provide an estimate when a system could be delivered for shipboard test. 2) Describe ability to counter the threat with both the baseline system and the variant systems. Provide supporting data and/or analysis including any underlying assumptions including gun dispersion, system errors, system reaction time, burst size, hits required to defeat the threat, etc. 3) Identify ammunition caliber/types used in above analysis. Please state if the ammunition and weapon is qualified for use aboard U.S. Navy ships. If not qualified, please provide any tests conducted which would support qualification for use aboard U.S. Navy ships. 4) Describe the casualty mode operation, i.e. ability to counter the threat should 1) power to weapon be lost or 2) loss of ability to control the weapon remotely is lost. 5) Provide Rough Order of Magnitude (ROM) System Cost in FY 98 dollars based upon a total procurement of 600 systems at a rate of 100 systems/year starting in FY 02. Please provide a breakout/matrix showing the costs of the major system components for both the baseline system and the two variants. Also provide cost of ammunition caliber/types used with system. Also provide total ownership costs based upon a useful service life of 20 years. 6) Provide data or analysis on the system Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR). Also, please describe any unique system attributes that would reduce susceptibility to corrosion. Companies are also requested to comment on the following issues: What are the risks associated with this effort? Are there unclear or inconsistent requirements? Is equipment in production or pre-production and available for live fire evaluation? Are there any overly restrictive requirements that would eliminate yoursystem from competition, or requires additional development effort to comply? Identify workable and efficient alternatives. Interested companies should respond with information within 45 days to the code and address shown above. THIS IS A REQUEST FOR INFORMATION ONLY. NAVSEA WILL NOT AWARD A CONTRACT ON THE BASIS OF THIS REQUEST. The Navy will utilize this information to further refine requirements and may in the future solicit competitive offers from those firms capable of providing an off-the-shelf NDI CIGS for a live fire evaluation Posted 08/11/98 (W-SN235236).
