2 Government and Commercial are Symbiotic

• Government experience facilitated development and successful flight demonstration of components later used in commercial systems

• Significant current synergy with NASA and defense programs enables economies of scale

3 Northrup Grumman Space Launch Services

• Active Launch Vehicle Programs ‒ Pegasus: Proven class 3 air-launch ‒ Minotaur USAF: Tailorable government launch ‒ Minotaur Commercial: Affordable commercial small launch ‒ Antares: International Space Station cargo resupply

• New launch system under development (intermediate and heavy class)

• Northrop Grumman space launch programs serve DoD, NASA and commercial markets

4 Successful NASA/Commercial Partnership

• Successful COTS development and CRS-1 cargo delivery

• More than 50,000 lbs. delivered to date

• Optimized volume solution provides maximum utility

• Awarded multiple follow-on missions including at least six CRS-2 missions
