Falcon Heavy Extended Fairing
From the new Falcon Users Guide: 5.2 x 18.7m. The standard fairing is 5.2 x 13.1m.
Required for National Security Space Launch (NSSL) the extended fairing would mainly be used for the big DoD spy satellites. It'll also be used for very long NASA payloads, such as launching the Lunar Gateway's Power & Propulsion Element already attached to the HALO habitat, rather than launching them separately.
Falcon 9/Falcon Heavy vehicle height
Standard: 70m
Extended: 75.2m
"SpaceX can also provide an extended fairing as a nonstandard service. The extended fairing has the same diameter as the standard faring (5.2 m, 17.2 ft) and an overall height of 18.7 m (61.25 ft)."
