JT Precision Approach & Ldg Sys
Abstract
A. Mission Description and Budget Item Justification The Joint Precision Approach and Landing System (JPALS) is an Acquisition Category 1D program with joint partners for requirements and acquisition including the USAF, USN/ USMC, USA, USCG, and the Federal Aviation Administration (FAA). JPALS is the next generation global positioning system (GPS)-based precision approach and landing system for the DoD and is intended to provide a rapidly deployable, adverse weather, adverse terrain, day/night precision approach and landing capability for fixed and rotary wing manned and unmanned aircraft. On 16 March 2007, the JROCM approved the JPALS Capability Development Document and designated the Navy as the Lead Service. The Analysis of Alternatives was finalized in 3Q FY07. Milestone B was met 14Jul08. At Milestone B, the Milestone Decision Authority separated Increment (Inc) 1 into Inc 1A and Inc 1B. On 19Jan10, the JROC approved Inc 2 for the Land-Based System and designated the Air Force as the lead component for the Land-Based System. The DoN PALC Roadmap Study documents direction to re-scope JPALS to a single increment. As a result, JPALS Inc 1B was reduced in scope to support the F-35 Lightning II and Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS) programs as their primary landing system on aircraft carriers and amphibious assault ships. Accordingly, improvements will be made to JPALS to provide autoland capability for manned and unmanned aircraft, therefore, investments in aircraft software and avionics will continue, although retrofit of existing aircraft was removed from program requirements. In addition, JPALS Inc 2 was cancelled. The remaining re-scoped JPALS program efforts provide a strong technology basis for evolution should a requirement for JPALS on existing aircraft, fixed air bases, or expeditionary air fields re-emerge in the future. JUSTIFICATION FOR BUDGET ACTIVITY: This program is funded under ADVANCED COMPONENT DEVELOPMENT AND PROTOTYPES because it includes all efforts necessary to evaluate integrated technologies, representative models or prototype systems in high fidelity and realistic operating environment.

- Change Summary Explanation
- Technical: Not applicable. Schedule (project 2329): Schedule has been revised to update program milestones. MS-C moved from first quarter FY2014 to second quarter FY2017 as a result of the Precision Approach and Landing Capability (PALC) Roadmap restructure of JPALS into a single increment and the inclusion of manned and unmanned autoland capabilities. Engineering and Manufacturing Development (EMD) phase extended to third quarter FY2016. Additional System Development and test events were added to support the revised program phasing and additional development for manned and unmanned autoland capabilities. LRIP contract award moved from third quarter FY2014 to third quarter FY2017. Added schedule elements to this project to depict the de-scope of JPALS to a single project for Increment 1. Schedule (projects 3228, 3354): Per above PALC changes, JPALS is now combined into a single project. Cost (project 2329): Per 2329 schedule discussion, all of JPALS will be consolidated into Project 2329. FY15 budget profile has been reduced to account for the re-structured JPALS program, brought on by the PALC Roadmap Study. Existing FY14 funding in projects 3228 and 3354 will carry over into FY15; FY 15 funding request (and $141.8M reduction from PB 14) reflects this assumed carryover. During FY 14 execution, funding will be realigned from projects 3228 and 3354 to project 2329.
