Overview: (U)
(U) The Titan IV is a heavy-lift space launch vehicle used to carry DoD payloads such as Defense Support Program (DSP) and Milstar satellites into space.  The Titan IVA vehicle configuration consists of a two stage liquid propellant core with a pair of large, attached solid rocket motors which provide the initial boost stage after lift-off.

Description: (U)
(U) The Titan IV was designed to complement the National Space Transportation System  (STS) (shuttle, orbiter) and serve as an independent launch vehicle system to assist in assuring Department of Defense (DoD) access to space. The Titan IVA is essentially a derivative of the 34D with structural extensions and other modifications to the two stage liquid propellant core vehicle designed to accommodate 2 seven-segment SRMs. The Titan IVA provides STS-equivalent and greater payload-to-orbit performance, enabling it to meet unique DoD requirements. 

(U)  All future launches of the Titan IV's will use the "B" version. 

User Impact: (U)
(U) Provides heavy-lift capability to launch surveillance, tracking, and communications satellites which support DoD and national requirements.
