CH-53K
Abstract
The CH-53 is the only marinized heavy-lift helicopter in the world and is the Marine Corps only heavy-lift helicopter. The CH-53 mission is the conduct of expeditionary heavy-lift assault transport of armored vehicles, equipment and personnel to support distributed operations deep inland from a sea-based center of operations. The CH-53E "Super Stallion" was introduced into operations in 1980 as an upgrade version of the CH-53D. The CH-53E has developed performance degradation, fatigue life, interoperability, maintenance supportability, and other operational concerns. An improved CH-53 is needed to support Marine Air-Ground Task Force heavy-lift requirements in the 21st century joint environment. The CH-53K "King Stallion" will provide improvements in range and payload, performance, cargo handling, turn-around times, reliability and maintainability, interoperability, and survivability. The CH-53K program is required to provide full system capability, including shipboard compatibilities, at Initial Operational Capability (IOC). Total aircraft quantities for the CH-53K program are 205 helicopters. This includes one Ground Test Vehicle (GTV) and four Engineering Development Models (EDMs) for System Development and Demonstration (SDD), to be purchased with Research, Development, Test & Evaluation (RDT&E) funds. Of the remaining 200 aircraft, six will be System Demonstration Test Articles (SDTAs) and will be incrementally funded using RDT&E funds. The SDTAs will be used to prove out production and integration processes on a pilot production line, and to provide aircraft for Initial Operational Test and Evaluation. The remaining 194 aircraft will be Aircraft Procurement, Navy funded. FY18 RDT&E funds CH-53K SDD activities which include: ground and flight test of GTV, EDMs and SDTAs, associated subsystems and components, and the continued fabrication and assembly of the remaining three SDTA aircraft. JUSTIFICATION FOR BUDGET ACTIVITY: This program is funded under SYSTEM DEVELOPMENT AND DEMONSTRATION because it includes those projects that have passed Milestone B approval and are conducting engineering and manufacturing development tasks aimed at meeting validated requirements prior to full-rate production decision. ***Note*** $53.000M FY16 RDTE is encumbered in support of JUONS-S0-0010, entitled 'Federated Distributed Aperture Infrared Countermeasures' (DAIRCM) via Rapid Acquisition Authority with a planned contract award in September 2016.

- Change Summary Explanation
- Technical: FY 2018 funding level increases by $106.600M in order to fully-fund to the Navy's CH-53K Milestone C Component Cost Position in support of CH-53K SDD efforts to include flight test and Prime Contractor fabrication and assembly of SDTA 4-6. Schedule: Full Rate Production (FRP) has moved from 2Q FY2020 to 1Q FY2021 to allow for completion of LFT&E program and receipt of test report. Initial Operational Test & Evaluation (IOT&E) start date moved from 2Q FY2019 to 4Q FY2019 due to discovery during flight test and to incorporate the required corrections.
