"The USMC has added STOVL performance as a service specific key performance parameter. The requirement is listed as follows: With two 1000# JDAMs and two internal AIM-120s, full expendables, execute a 550 [now 600] foot (450 UK STOVL) STO from LHA, LHD, and aircraft carriers
(sea level, tropical day, 10 kts operational WOD) & with a combat radius of 450 nm (STOVL profile). Also must perform STOVL vertical landing with two 1000# JDAMs and two internal AIM-120s, full expendables, and fuel to fly the STOVL Recovery profile = ["...2,200 lbs of fuel for an approach, vertical landing, and reserve (Killea) see below]."

STOVL JSF DESIGN REQUIREMENTS [pages 5-6]
The design requirements for the STOVL JSF mandated a Vertical Lift Bring Back (VLBB) capability of 5,000lbs of fuel and ordnance on a tropical day. The STOVL JSF’s empty gross weight is 29,735 lbs, and it is equipped with a lift fan design capable of producing 39,800 lbs of vertical lift at sea level on a tropical day. An ability to produce 39,800lbs of thrust minus 29,735 lbs gross weight and 3,000 lbs of thrust to safely maneuver the aircraft equals 7,065 lbs of VLBB. As a result the STOVL JSF thirty percent more VLBB then the requirements document mandated (Killea). This means in a worst case, sea-based scenario the STOVL JSF is more than capable of conducting a vertical landing with 4,000 lbs, vise 2,000 lbs, ordnance, plus two 325-lb radar missiles, and 2,200 lbs of fuel for an approach, vertical landing, and reserve (Killea)....”
