Taurus II Program Highlights

Designed to Provide Delta II-Class Payload Performance at All-Inclusive Launch Prices of ~$65 Million With High Mission Reliability and Responsiveness

Orbital Is Applying Its Well-Established Engineering, Manufacturing, Supplier Management, Mission Assurance and Program Management Capabilities to Develop, Qualify, Produce and Operate the Taurus II Vehicle Taurus II Is Based on a High-TRL Design to Minimize Development and Early-Flight Risk, While Also Using Selected Non-Traditional Suppliers and a Lean Fixed Infrastructure to Maintain Attractive Launch Costs

Designing to Provide Launch Services for a Variety of Different MissionsNASA Science/Planetary and Space Station Resupply; NASA Cat. 3 ReliabilityDoD/IC Gapfillers, Demos, Space Superiority, and Medium-Class MissionsOperationally Responsive SpaceCommercial LEO and GEO

Taurus II Is On Schedule for Its First Launch(es) in Late 2010 and Will Be Capable of Supporting Up to 6 Launches per Year By 2012Orbital and Our Partners Are Investing ∼$200 Million of Our Own Capital to Fund Taurus II Development, Support Equipment, Production Inventory and Launch Site Infrastructure

Taurus II Will Be Ready to Fill the Medium-Class Satellite “Launch Gap” by 2010


Taurus II Vehicle Overview

Program Goals• Minimize Development NRE -- Select High TRL

Components or Components Already Under Development• Minimize Recurring Costs -- Eliminated Strap-on Booster

Rockets• Meet or Exceed Delta II Performance Parameters -- Drove

Environments, Payload Volumes, and Performance• Minimize Launch Site Infrastructure – Use Horizontal

Integration/Spartan Pad Concept• Design for High Reliability -- Use Heritage Components
