Gregory D English

Gregory D. English serves as Chief of the E-3 KC-135 Contracting Branch, overseeing the acquisition and lifecycle support of critical airborne command, control, and aerial refueling platforms for the U.S. Air Force. In this leadership role, he directs the planning, solicitation, and contract administration for complex aerospace systems, ensuring compliance with federal acquisition regulations and mission-critical readiness requirements. His portfolio centers on sustaining and modernizing the E-3 Sentry and KC-135 Stratotanker fleets, coordinating with engineering, logistics, and program management teams to align procurement strategy with operational needs. His work is foundational to maintaining the Air Force’s global air mobility and battle management capabilities. Mr. English’s contracting activities primarily involve direct award contracts with prime contractors specializing in aerospace systems integration, propulsion, avionics, and maintenance support. While no specific vendor relationships are highlighted, his office consistently engages with Tier 1 defense aerospace manufacturers and specialized maintenance, repair, and overhaul (MRO) providers with deep expertise in military aircraft platforms. His procurement patterns reflect a preference for established, qualified vendors with proven track records in sustaining legacy military aircraft systems under stringent performance and security standards. His set-aside preferences are overwhelmingly dominated by non-set-aside acquisitions, with only 1.7% of awards designated for total small business set-asides under FAR 19.5. This reflects the technical complexity and scale of the systems he manages, which often require specialized capabilities beyond the capacity of most small businesses. Nevertheless, he maintains a structured approach to small business participation where feasible, ensuring that subcontracting opportunities are appropriately leveraged in larger contracts. Mr. English’s procurement focus is concentrated in NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing), accounting for 95.7% of his activity, underscoring his deep technical expertise in propulsion systems, engine overhaul, and powerplant sustainment. Secondary focus areas include other engine equipment manufacturing and specialized communications infrastructure. His domain expertise lies in the sustainment of turbofan and turboshaft propulsion systems, flight control integration, and mission system upgrades for strategic airlift and airborne command platforms.
