This is a market survey covering a Doppler Navigation Set (DNS), procured previously as AN/ASN-157, contained in a single Line Replaceable Unit (LRU). This action is not a request for proposal and does not commit the Army to procurement of this set. The Army has a requirement to purchase an additional quantity of approximately 348 AN/ASN-157 DNSs (including spares) over a 5 year period for use in the AH-64C/D Longbow Apache Helicopter. Prototype installation in the AH-64 Longbow Apache helicopter has been accomplished for the AN/ASN-157. A production line has been established and first article acceptance qualification testing has been completed. Delivery of this final lot is scheduled to commence in June 2000. Additional DNSs are required for delivery commencing July 2001 at an initial rate of 6 sets per month. The equipment offered in response to this market survey is required to meet the Government Performance Specification, MIL-PRF-XXXXX, for the AN/ASN-157 Doppler Navigation Set and the provisions of Installation and Acceptance Test Document AV-IT5845-001A. Only those offerors who can meet the total technical and delivery requirements with a fully qualified ASN-157 DNS that meets Form, Fit and Function requirements should respond. Offerors must provide proof of their ability, in response to this market survey, to the procuring activity no later than 30 days following publication in the CBD. The Government is not planning a qualification test of equipment prior to Formal Solicitation. Offerors proof of their ability to meet Government requirements shall, as a minimum, include the following: a. Equipment availability and validated bench and flight (helicopter) test data to show the offeror's capability to meet Apache Longbow operational requirements. b. Availability of operational manuals (draft manuals acceptable). c. Ability to meet government total delivery requirement commencing 11 months after award of contract at a rate of 6 sets per month through the 5 year of the contract. The production DNS to be procured, in response to the formal Army solicitation shall, as a minimum, have the following capabilities: (1) Meet the requirements of the government Product Performance Specification, MIL-PRF-XXXXX, dated 10 June 1999 for the AN/ASN-157 Doppler Navigation Set and the provisions of Installation and Acceptance Test Document AV-IT-5845-001A.
