Alainna M. Pettit serves as a key procurement professional within Navsup Weapon Systems Support, supporting the Department of the Navy’s mission to sustain and modernize naval aviation and weapon systems. She manages complex acquisitions for mission-critical components, including aircraft subsystems, avionics, power generation equipment, and specialized electronics essential to operational readiness. Her work ensures the continuous availability of spare parts and upgraded systems for legacy and next-generation platforms, aligning with strategic priorities in supply chain resilience and technical modernization. Pettit handles a high-volume portfolio of sole-source and competitive contracts, often requiring technical evaluation and engineering collaboration to meet stringent military specifications. She maintains long-standing relationships with leading defense contractors including Northrop Grumman Systems Corporation, Thales Defense & Security Inc., and Hamilton Sundstrand Corporation, partnering with firms that provide advanced aerospace components and mission-critical subsystems. These vendor relationships are characterized by deep technical alignment, sustained performance histories, and frequent recompete contracts for sustainment and obsolescence management. Pettit’s procurement approach emphasizes reliability, technical compliance, and lifecycle support over cost alone, favoring established industry leaders with proven capabilities in naval aviation environments. Pettit’s contracting activity reflects a strict focus on open competition, with 100% of awards issued without set-aside designations such as 8(a), HUBZone, or SDVOSB. This indicates a procurement strategy prioritizing technical necessity and supply chain continuity over socioeconomic preferences, consistent with the specialized nature of weapon systems sustainment where certified small businesses are rarely qualified to meet the required performance standards. Her primary procurement focus lies in NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), with significant activity in 336412 (Aircraft Engine and Engine Parts Manufacturing) and 333998 (Miscellaneous General Purpose Machinery). She routinely acquires high-integrity components such as flight control actuators, environmental control units, and mission electronics, demonstrating deep expertise in aerospace systems engineering and defense logistics.
