With a wingspan of 72.38 feet (22 meters) and a length of 43 feet (13.1 meters), it offers a maximum payload capacity of 5,070 pounds (2,300 kilograms) and a range of up to 1,070 nautical miles (1,982 kilometers) when carrying a 2,000-pound (907-kilogram) payload.
History of the Development of the SNC MC-145B Wily Coyote
In the early 21st century, military operations increasingly required aircraft capable of performing multiple roles, especially in austere and unpredictable environments. The need for a versatile platform that could conduct airdrop missions, ISR, and medevac operations became evident. To address this requirement, Sierra Nevada Corporation (SNC), in collaboration with PZL Mielec, initiated the development of the MC-145B Wily Coyote.
The MC-145B is an enhanced version of the PZL M28 Skytruck, a twin-engine turboprop utility aircraft known for its STOL capabilities. The M28 itself was developed from the Soviet-era Antonov An-28 and had seen service in various roles worldwide. Recognizing the potential of the M28 platform, SNC and PZL Mielec sought to create a multi-role aircraft tailored to the needs of special operations forces.
In May 2021, the U.S. Special Operations Command (USSOCOM) launched the Armed Overwatch program, aiming to acquire a new manned light attack aircraft to support special operations forces in permissive environments. SNC and PZL Mielec entered the MC-145B into this competition, highlighting its multi-role capabilities and suitability for diverse mission profiles.
The MC-145B was designed to address specific operational needs identified during conflicts in the Middle East and other regions. These conflicts underscored the importance of having aircraft capable of operating from short and unprepared airstrips, delivering precision strikes, and conducting ISR missions. The MC-145B’s development focused on creating a platform that could be rapidly reconfigured for various missions, reducing the logistical footprint and increasing operational flexibility.
The aircraft’s first flight occurred in 2021, marking a significant milestone in its development. Following its maiden flight, the MC-145B underwent a series of evaluations and demonstrations to showcase its capabilities to potential operators, including USSOCOM. These demonstrations highlighted the aircraft’s ability to perform airdrop missions, conduct ISR operations, and provide close air support with precision-guided munitions.
The name “Wily Coyote” reflects the aircraft’s intended role as a cunning and adaptable platform, capable of performing a variety of missions in challenging environments. The moniker draws inspiration from the resourceful cartoon character, symbolizing the aircraft’s versatility and agility.
Throughout its development, the MC-145B benefited from the combined expertise of SNC and PZL Mielec. SNC brought experience in integrating advanced avionics, communication systems, and mission-specific equipment, while PZL Mielec contributed its knowledge of airframe design and manufacturing. This collaboration resulted in an aircraft that leverages the strengths of both companies to meet the evolving needs of special operations forces.
The MC-145B’s development also considered the importance of interoperability with existing military assets. The aircraft was designed to operate seamlessly with other platforms, sharing data and coordinating missions to enhance overall operational effectiveness. This focus on interoperability ensures that the MC-145B can integrate into joint and coalition operations, providing a force multiplier effect.
As of 2021, the MC-145B was undergoing further testing and evaluation as part of the Armed Overwatch program. The outcome of this program would determine the aircraft’s future role within USSOCOM and its potential adoption by other military forces seeking a versatile and adaptable multi-role platform.
