IISA (Integrated Inertial Sensor Assembly) and Conventional Equipment Cost Comparison

摘要

This study contains a hardware (avionics) cost comparison of the systems required to perform navigation, flight control, weapon delivery and sensor stabilization functions on modern naval aircraft. The Air Navigation Systems Development Branch (Code 4011) of the Communication Navigation Technology Directorate (Code 40) at the Naval Air Development Center has tasked the Weapon System Cost Analysis Branch (Code 7023) to develop an independent cost study to compare conventional systems for navigation, flight control, weapon delivery and sensor stabilization currently targeted for conventional next generation Navy aircraft, with a potential replacement system, IISA. This report compares a proposed new Integrated Inertial Sensor Assembly System (IISA) as a potential replacement for proposed conventional systems (ASW-44, LR-85, ASN-139 and USN-2) planned for use on the next generation aircraft. Contained in this report are cost estimates based on technical analysis for both systems (IISA/Conventional) in the Production and Operating & Support (O&S) phases of their programs. Aircraft lot quantities of 300, 500 & 1000 are assumed. The Production/0&S cost results are presented and documented. (KR)
