• Current Navy– 281 ships in our fleet– Fleet Response Program stresses them all– Our Job: Fix them quickly, get them back on line, tackle the HARD
issues
• Next Navy– 29 Major design, conversion projects – $13 + billion per year– Our Job: Correct, accurate designs: review approve, certify
• Navy After Next– “What – if” studies for the Navy’s leadership – Satisfy the needs 20-50 years in the future– Our Job : Think out of the box; be the world leader
