The U.S. Air Force Life Cycle Management Center (AFLCMC) at Wright-Patterson AFB, Ohio is planning to certify new self-protection materiel for Boeing [BA] KC-46 tankers with the Remote Vision System (RVS) 1.0 and to field a new self-protection design under RVS 2.0, AFLCMC said.
“KC-46 Force Protection Key Performance Parameter is not currently compliant across the fleet due to supply material becoming obsolete in 2022,” AFLCMC said in an email response to questions. “A corrective action plan will certify new material in 2024 for RVS 1.0. A unique solution will be fielded with RVS 2.0.”
Defense Daily will update this article with anything further received on the supplier or suppliers of the obsolete material and the “unique solution.”
In the first quarter of 2019, the KC-46A program conducted a system verification review that laid out aircraft shortcomings in meeting self-protection requirements related to RVS and the use of Long-Wave Infrared (LWIR) “in hostile environments,” according to a DoD Selected Acquisition Report released last year.
“Redesign efforts are currently underway to improve functionality of RVS to meet Critical Performance Parameters in order to resolve non-compliances enabling LWIR functionality,” the report said. “At completion, we will provide demonstrated performance for KPP [key performance parameter].”
Boeing and its Aurora Flight Sciences subsidiary are working on self-protection improvements for the Boeing KC-46A Pegasus and future tankers, Boeing said last week at the Paris Air Show (Defense Daily, June 20).
Boeing and Aurora “are investing in further developing advanced defensive systems and countermeasures for application on next-generation refueling and mobility platforms including the KC-46A Pegasus tanker,” Boeing said.
Aurora “is leading the research and conceptual design of composite components to enhance operational survivability for aerial refueling and mobility missions,” Boeing said. “This work will also focus on producibility and manufacturing at Aurora’s Columbus, Miss., manufacturing facility.”
The KC-46A is equipped with Northrop Grumman’s [NOC] AN/AAQ-24(V) Large Aircraft Infrared Countermeasures (LAIRCM) and Raytheon Technologies‘ [RTX] ALR-69A radar warning receiver.
The Air Force requests about $3 billion in fiscal 2024 for 15 KC-46As.
“Operationally deployed for global combat operations, the KC-46A features defensive systems and data integration for multi-mission aerial refueling support closer to the battlespace than existing tankers,” Boeing said last week. “With more data for the crew and fleet, including recent Block 1 upgrades to further enhance connectivity, the Pegasus can see and relay threat information to joint force warfighters for greater fleet survivability and mission success.”
The end of KC-46A initial operational test and evaluation and a full-rate production decision for the KC-46A are not expected until fiscal 2024 at the earliest because of redesign efforts related to past problems with RVS 1.0, the refueling boom, the modified ALR-69A RWR and the Tactical Situational Awareness System (TSAS) by Raytheon’s Collins Aerospace (Defense Daily, March 31, 2022).
Boeing said last week that it plans to leverage Aurora’s experience with the U.S. Navy’s MQ-25 Stingray. Aurora’s Columbus, Miss., location “specializes in producing composite components and sub-assemblies for the aerospace industry, such as the composite skin for Boeing’s MQ-25 Stingray, the world’s first autonomous aerial refueler, which provides lightweight strengthening and anti-corrosive benefits that are crucial for the carrier-based aircraft,” Boeing said.
The U.S. Air Force may decide this summer on a buy of up to 75 tankers to fill the gap between the planned fielding of the 179th and final KC-46A Pegasus in 2029 and the fielding of the Next-Generation Air Refueling System (NGAS) in the mid-to-late 2030s (Defense Daily, Apr. 6).
The service wants to conduct an Analysis of Alternatives on NGAS and has decided to end the KC-Y program for buying 150 commercial tankers as a bridge to NGAS–formerly known as KC-Z.
