C. ROCKET SYSTEMS (including ballistic missile systems,space launch vehicles and sounding rockets) and Unmanned Air Vehicles (UAV) (including cruise missiles, target drones, and reconnaissance drones): Technologies associated with rocket systems and UAV systems. The technology needed to develop a satellite launch vehicle is virtually identical to that needed to build a ballistic missile.
D. ROCKET SYSTEM AND UNMANNED AIR VEHICLE (UAV) SUBSYSTEMS:

Propulsion technologies include solid rocket motor stages,and liquid propellant engines. Other critical subsystems include re-entry vehicles, guidance sets, thrust vector controls and warhead safing, arming and fusing. Many of these technologies are dual-use. Technologies include:

-- Liquid and solid rocket propulsion systems

-- Missile propulsion and systems integration

-- Individual rocket stages or staging/separation mechanism

-- Aerospace thermal (such as superalloys) and high-performance structures

-- Propulsion systems test facilities

E. NAVIGATION, AVIONICS AND FLIGHT CONTROL USEABLE IN ROCKET SYSTEMS AND UNMANNED AIR VEHICLES (UAV): These capabilities directly determine the delivery accuracy and lethality of both unguided and guided weapons. The long-term costs to design, build and apply these technologies have been a limiting proliferation factor. Technologies include those associated with:

-- Internal navigation systems

-- Tracking and terminal homing devices

-- Accelerometers and gyroscopes

-- Rocket and UAV and flight control systems.

-- Global Positioning System (GPS)
