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

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 TestTest Article Mounted To Pad

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

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

Orbital ATK Will Be Ready to Restart Cargo Deliveries

to the ISS with Antares Later This Year
