(1/ Includes cost of overhauls which are reflected in the Additional Cost Section of the SAR.) Explanation of Difference Between FY 1973 and FY 1974: Net reduction of $104.1 million is the result of inclusion of recent cost experience for converting submarines to POSEIDON capability. The POSEIDON conversion program does not represent a major new development effort, but rather is a follow on development to the successful "POLARIS" Fleet Ballistic Missile Weapon System effort, employing the same general technical control proved effective in the original construction of the SSBN with the installed subsystems. The vast majority of these subsystems have been previously installed and tested with results fully confirmed in operations. The POSEIDON Weapon System consists of seven major subsystems. These are Ship, Missile, Guidance, Fire Control, Navigation, Major development agencies and contractors associated with development of the FBMWS under the Launcher, and Test Instrumentation. technical direction of the Strategic Systems Projects Office include: AGENCIES/CONTRACTORS Naval Material Command (SHIPS 08) Atomic Energy Commission Naval Ships System Command Electric Boat Division, General Dynamics Corporation Newport News Shipbuilding & Drydock Company In addition to historical detailed development tests which have provided valuable experience and a basis for continued Subsequent to the installation of various equipments and subsystems into each FEM submarine during conversion or overhaul and A seven phase Shipyard numerous other inspections Program (81TP) consisting of more than one Installation Teat and checks hundred and ninety separate formal tests has been employed Batinfactorily in the past and 10 planned for FY 1974 shipyard installa Phase 1 Inspection relates to the shipyard inspection of all new, relocated or re-installed FBM WS equipments Visual checks of electrical systems are made to verify equipment has been installed such as cabling, piping and subsystem components. Also, continuity checks are conducted to verify continuous electrical path through in accordance with applicable drawings. A visual check is made of equipment arrangements, orientation and clearance. individual conductors. Phase 2 Static Tests include all tests which prove the integrity of the individual ship electrical power supplies Power distribution cables are checked for isolation to ground by measuring insulation resistance after hook-up. and piping systems. Ship electrical power supply circuits are energized and checked for proper voltage, frequency, and/or phase rotation, as applicable. Phase 3 Grooming Tests include checks of initial operation of individual equipments, individual loops within the subsystem, and individual loops between associated subsystems where feasible. Tests are conducted to insure satisfactory operation of all subsystem equipment and all subsystem circuits. Controls, displays, sequencing, alarms and instrumentation are checked in all required modes of operation. Safety devices are set to specified values and checked for proper operation. Phase 4 Subsystem Operational and Performance Tests demonstrate that the subsystem and its components operate and perform within specified tolerances in normal, casualty, and test modes. Tests are conducted both dockside and under sea conditions located in the vicinity of the shipyard. Phase 5 System Interface Tests demonstrate that proper mechanical, electrical, fluid and optical inter-connection and transmission exits between subsystems. These tests include both static verification and dynamic verification of the characteristics of these individual functions and wherever necessary system performance parameters are analyzed to assure compliance with tolerances specified. Phase 6 System Operational and Performance Tests demonstrate operability and performance, in as nearly tactical closed loop configurations as is possible, at both dockside and under sea condtions located in the vicinity of the shipyard. performance parameters are analyzed to assure compliance with tolerances specified. System Phase 7 Post Shakedown Availability Tests are conducted after completion of Demonstration and Shakedown Operation (DASO). These tests verify weapon system integrity after removal of non-tactical test equipment and verify the correction of problems detected during the DASO operations. (2) Demonstration and Shakedown (DASO) DASOS are accomplished subsequent to each Phase 6 SITP test. The objective of the DASO is to demonstrate the readiness of POSEIDON Weapon System and its crew for deployment. A DASO requires approximately four (4) weeks for each of its two crews and exercises the complete POSEIDON system in a comprehensive series of subsystem and system tests. The overall DASO test program consists of four types of operations conducted at the Charleston Missile Facility, alongside in Port Canaveral, and at sea on the Eastern Test Range; 1.e., Navigation tests, Preparation and Readiness Evaluation (PREP), Tactical Exercises, and weapon System |
