Sustaining a highly skilled and mission-ready nursing workforce is essential to the success of the Military Health System (MHS). Yet many emerging military nurse officers enter service without access to structured mentorship, strategic career guidance, or a community of leaders who can accelerate their professional growth. Ready to Launch, a faculty-driven mentorship and professional development initiative, was established to address this gap—connecting aspiring and newly commissioned military nurses with senior nurse leaders across the Services. Now in its fifth year, the program has demonstrated powerful and measurable impact. Analysis of participation trends from 2020–2025 reveals a consistent rise in engagement, with nearly 30% of this year’s applicants reporting active involvement in a recent Ready to Launch program. Participants describe increased confidence, clearer career trajectories, and improved readiness for advanced practice roles. Across five years, the program has cultivated a diverse network of mentors and mentees who contribute directly to officer retention, leadership development, and improved care delivery in MTFs. This presentation highlights program outcomes, participant-driven insights, and emerging themes from qualitative reflections illustrating how mentorship transforms the early career experience of military nurse officers. Findings underscore mentorship as a strategic readiness multiplier—strengthening workforce stability, enhancing clinical and operational capability, and reinforcing the long-term vitality of the MHS nursing pipeline. Recommendations for scaling mentorship across federal health professions and integrating structured mentorship into force development strategies will also be discussed.
