Aircraft Carrier Roadmap

• LARGE-DECK, NUCLEAR- POWERED CARRIERS
• CORNERSTONE OF NAVAL AVIATION
• IMMEDIATE, FIRST DAY OF THE WAR RESPONSE
• LONG ENDURANCE ON STATION, SELF-RELIANT

• CVN 21 PROGRAM (CVN 78-CLASS)
• IMPROVED REACTOR, ELECTRICAL AUXILIARY SYSTEMS,
  EMALS
• NEARLY 300 INCREASE IN ELECTRICAL POWER
  GENERATION
• STATE-OF-THE-ART C2, LARGER FLIGHT DECK, AND
  ADVANCED ARRESTING GEAR

Why CVN 21 Program?
CVN 68-Class
CVN 78-Class
Increased Capability
Increased Flexibility
Increased Affordability

• Greater operational availability
• 3X electric plant capacity

• Sortie Generation Rates increased by 25

• 5B TOC reduction
• 500-900 billet reduction

• Survivability improvements
• Damage Control improvements
• Improved ship self-defense
• Increased magazine and AVGAS storage
• Interoperability (IER)

• Reduced construction costs
• Maintenance requirements reduced by 30
• Product Model Design

• Flexibility of open architecture
• Restoration of Service Life Allowances (Wt/Kg)
• Integration of future air platforms

Marks the first investment in a new design
aircraft carrier in 40 years!

CVN 78-class A Leap Ahead
Enhanced Flight Deck

• Advanced Arresting Gear
• Electromagnetic Aircraft Launch System

18
Electromagnetic Aircraft Launch System(EMALS)
Description and Status

• Electric power replacement for steam catapult
• Still operating with steam cats for next 50
  years
• EMALS integral to CVN 78 design
• Not backfittable in NIMITZ hulls
• Benefits
• Eliminates steam requirement
• Reduced manpower to operate/maintain
• Expanded launch weight range
