Titan IVB

Titan IVB was the upgraded Titan IV configuration with two three-segment Solid Rocket Motor Upgrades and a two-stage liquid-propellant core. Seventeen vehicles flew from 1997 through 2005. Every Titan IVB core completed powered flight; two 1999 missions subsequently failed during IUS or Centaur upper-stage operations.
