High Altitude ASW
Abstract
The P-8A High Altitude Anti-Submarine Warfare (HAASW) program objective is to ensure greater Anti-Submarine Warfare (ASW) aircraft operational flexibility and effectiveness at high altitudes. FY10-FY14 R&D monies fund necessary engineering changes to ASW sonobuoys, in addition to developing and integrating a meteorological sensing device (Dropsonde). Sonobuoys will be modified with a Global Positioning System (GPS) and a NATO standard Digital Uplink. GPS integration will provide precise sonobuoy location regardless of aircraft altitude/location to enhance wide area ASW search, localization, tracking, and targeting. The Digital Uplink will improve sonobuoy communications performance in high Radio Frequency Interference (RFI) littoral environments, increase Air Deployable Active Receiver channel availability, and provide NATO compatibility. The Dropsonde provides the capability to conduct in-situ meteorological (temperature, pressure, humidity, and winds) data measurement. The P-8A will use this real time data to update tactical decision aids, refine sonobuoy "release points", and for in-flight mission planning for optimization of Radar, Electo-Optical, Infra-Red, and other non-acoustic sensors. The FY11 test article quantities reflect 200 sonobuoys/dropsondes. Reduced test article quantities to reflect a more realistic schedule.
