2. CRS Return To Flight Plan
 The Orbital ATK Plan Has the Following
Elements:
 Return Antares to Flight Using New, In-
Production RD-181 Engines
 Launch Cygnus on the Atlas V 401 Launch
Vehicle during the Antares Down-time
− No Significant Atlas Modifications are
Required
 Increased Capability of Atlas V and the New
Antares With RD-181 Engines Allow the
Remaining 13,100kg Obligation to be Delivered
in 4 Missions
 1 Fewer Than the Original Planned 5 Missions
 Subsequent to the Above Plan, We Jointly Decided
With NASA to Convert the OA-6 Mission to an
Atlas V Mission as Well
 Increases Cargo Delivery to ISS During This
Critical Resupply Period by 300kg

Enhanced Cygnus

5. Antares 230 Configuration
Development Status Update
 Orbital ATK (OA) has developed a new configuration of Antares – the Antares 230
configuration – that features new stage 1 rocket engines
 RD-181 engines were selected as an ideal replacement for prior AJ26 engines
 Decision was made in consultation with our NASA customer and is now publicly
disclosed
 Directly addresses Orb-3 AIB corrective action #1
 The Antares 230 configuration will be capable of launching a 7000kg Cygnus
(carrying 3200kg of cargo) to ISS as early as May 2016
 Will use existing Stage 1 Core tanks with minor modifications necessary to
accommodate new RD-181 engines – and same upper stack used on Orb-3 with minor
avionics changes
 RD-181 engine development is complete and production is well underway
− Certification testing program complete
− First three flight engines completed acceptance testing and were delivered in July
2015
◦ Acceptance test profile is flight duration at flight power levels, which directly
addresses Orb-3 AIB corrective action #2
 A hot fire Stage Test at Launch Pad 0A in March 2016 will be the major system level
verification activity prior to the OA-5 mission
− The Stage Test will verify operation of the integrated first stage

 Stage Test Plan For The Upgraded Antares 230 is the Major
Verification Activity Prior to the OA-5 Return to Flight Mission
 The Stage Test Features Two Main Activities
 One Wet Dress Rehearsal (WDR)
 Verify And Demonstrate All Processes And Operations
Required To Properly Configure The Test Article For Engine
Ignition
 One Hot Fire Test
 Verify Operation And Performance Of Integrated First Stage
Featuring Upgraded Propulsion System
 Test Planning (Test Configuration, Schedule, Documentation,
Operations, Etc) Is Underway, Schedule Forecast: March 2016
 Test Article Assembly Has Begun
 Major Partners (NASA, MARS, Energomash, Yuzhnoye, Etc)
Have Been Briefed On Test Plan, And Are Working With
Antares Program In Various Roles To Prepare For The Test
Test Article Mounted To Pad

7. Pad 0A Repairs and Upgrades Completed
 All Concrete Structure Damage Has Been Repaired, Lightning Masts Replaced and Repair of
Damaged Fueling and Pressure System Piping is Complete.
 Modifications Required to Support RD-181 are Complete
 Modification and Testing of Transporter/Erector Launcher and Hydraulic Systems Complete
 Performance Testing of Pad Systems Completed

12. Summary
 Orbital ATK is Meeting its Commitment to NASA Under the CRS-1 Contract:
 Deliver the Remaining Cargo Obligation on the Original Contract by the End of 2016
 Deliver Additional Cargo in 2017 Via Extension Missions
 Purchase of Atlas V Missions Restarted Cargo Deliveries to ISS While Antares
Upgrade to the 230 Configuration is Completed
 Antares 230 configuration incorporates new-built RD-181 engines that are an ideal
replacement for the previous AJ26 engines
 RD-181 certification testing program has completed successfully
 RD-181 flight engines will be acceptance tested through a flight-representative profile
 Replacement of the AJ26 engines with the RD-181 engines fully addresses the AIB
recommended corrective actions
 Antares 230 and Pad 0A schedules support the Stage Test in March 2016 followed by
the OA-5 mission in 2Q2016 and OA-7 mission in 4Q2016
