Titan IV was a family of heavy-lift space launch vehicles developed by Martin Marietta and operated by the United States Air Force from 1989 to 2005. [4] Launches were conducted from Cape Canaveral Air Force Station, Florida [5] and Vandenberg Air Force Base, California.
Titan was a family of United States expendable rockets used between 1959 and 2005. The Titan I and Titan II were part of the US Air Force's intercontinental ballistic missile (ICBM) fleet until 1987. The space launch vehicle versions contributed the majority of the 368 Titan launches, including all the Project Gemini crewed

Titan's dense atmosphere and low gravity mean that the flight power for a given mass is a factor of about 40 times lower than on Earth. [3] The atmosphere has 1.45 times the pressure and about four times the density of Earth's, and local gravity (13.8% of Earth's) make flight easier than on Earth, although cold temperatures, lower light levels ...

In a test flight for endurance, the aircraft remained airborne and fully operational for 35.4 hours. It is designed to be able to remain airborne for a full week in the event of an emergency. [12] It takes two fully loaded KC-135 tankers to fully refuel an E-4B. The E-4B has three operational decks: upper, middle, and lower. [citation needed]
Before the end of 1994, the booster had finally been qualified for flight. [18] By 1994, it had become apparent that Martin Marietta's additional order for UA1207 boosters, combined with a decline in demand for launches, was resulting in a surplus of completed Titan IV carrier rockets. [16] As a result, the SRMU would not be needed until 1997.
