South Korea Selects Sikorsky S-92A+ for Presidential Helicopter Fleet

South Korea's Defense Acquisition Program Administration has officially selected Sikorsky to supply four next-generation S-92A+ helicopters for the Republic of Korea Air Force under the Presidential Helicopter II program. The procurement, valued at approximately 873 billion won (US$610 million), will replace the country's existing presidential transport fleet, which has operated three baseline S-92 helicopters since 2007. Deliveries and the operational transition are scheduled to begin around 2031, expanding the head-of-state rotary fleet from three to four airframes.

The decision concludes a competitive evaluation initiated in April 2025, when South Korean defense authorities approved the acquisition of new VIP transport aircraft. During the evaluation process, defense procurement officials reviewed the Sikorsky S-92A+ alongside the Airbus H225M, Leonardo AW101, and Bell 525. Competing airframes were ultimately disqualified over pricing and technical requirement thresholds, leaving Sikorsky as the sole eligible bidder when the Defense Acquisition Program Promotion Committee granted formal approval on 6 November.

Upgraded Architecture and Powerplants

The S-92A+ represents a modernized variant of Sikorsky's twin-engine medium-lift helicopter, incorporating structural and mechanical upgrades designed to improve performance in demanding operational environments. The aircraft is equipped with upgraded General Electric CT7-8A6 turboshaft engines and the S-92 Phase IV main gearbox, which features an auxiliary lubrication system capable of extending operation in the event of primary oil pressure loss.

The variant also integrates Gross Weight Expansion enhancements, allowing for increased payload capacity or extended range through auxiliary fuel carriage. Sikorsky is producing the S-92A+ across its manufacturing facilities in Stratford, Connecticut, and Owego, New York, maintaining an annual production capacity of up to 12 aircraft. Worldwide, more than 300 S-92 helicopters have been delivered to operators in 28 countries, accumulating over 2.6 million flight hours with a fleet availability rate exceeding 90%.

Domestic Systems Integration and Maintenance

Under the contract structure, local aerospace industry participation plays a central role in delivering the completed aircraft. Korea Aviation Engineering and Maintenance Service (KAEMS), a maintenance, repair, and overhaul subsidiary of Korea Aerospace Industries, will perform in-country mission equipment completion on all four helicopters. This work package includes installing specialized head-of-state cabin interiors, sovereign satellite communications, and integrated electronic warfare self-protection suites.

The agreement also establishes comprehensive long-term sustainment support within South Korea, covering critical spare parts provisioning, tooling, technical publications, and embedded field service engineering support. In addition to presidential transport, S-92 variants are operated domestically by the Korea Coast Guard for maritime search and rescue and by the National 119 Rescue Headquarters for emergency medical evacuation and disaster response missions.

Operational Redundancy in Executive Transport

Expanding the presidential detachment from three to four airframes addresses specific operational doctrine governing executive airlift. High-security presidential movements typically deploy multiple helicopters simultaneously, using decoy formations and airborne spares to disguise the head-of-state's exact location while providing immediate backup in the event of an in-flight abort or diversion.

South Korea becomes the latest government to commit to the S-92 family for head-of-state transport, joining 13 other nations that deploy the type for executive travel. The platform also provides the baseline airframe for the United States Marine Corps' VH-92A Patriot, which entered White House presidential service following specialized modifications for presidential transport.
