Lockheed Martin F-35 Lightning II
The Joint Strike Fighter (JSF) Program, formerly the Joint Advanced Strike Technology (JAST)
Program, is the Department of Defense's focal point for defining affordable next generation strike
aircraft weapon systems for the United States Navy, Air Force and Marines, and several allied
At present Great Britain, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway are
involved in the program and committed to adopt the F-35, while other countries are likely to join in the
The focus of the program is affordability - reducing the development cost, production cost, and
cost of ownership of the JSF family of aircraft.
The JSF will fulfill stated Service needs as follows:
• U. S. Navy First day of war, survivable strike fighter aircraft to complement F/A-18E/F
• U.S. Air Force Multirole aircraft (primary-air-to-ground) to replace the F-16 and A-10 and
complement the F/A-22
• U.S. Marine Corps STOVL aircraft to replace the AV-8B and F/A-18 as their only strike fighter
• United Kingdom Royal Navy & Royal Air Force STOVL aircraft to replace Sea Harriers & GR.7s as
a supersonic strike fighter
• Other Countries Potential JSF customers include current operators of F-16, F/A-18, and AV-8B released June 10, 2013
IMPORTANT! This add-on is designed to work with FLIGHT SIMULATOR X
with the ACCELERATION package installed. Flight Simulator X AND the
ACCELERATION package (or Flight Simulator X:Gold Edition) are REQUIRED.
The F-35C carrier variant has a larger, folding wing and larger control surfaces for
improved low-speed control, and stronger landing gear and hook for the stresses of carrier
landings. The larger wing area allows for decreased landing speed, increased range and
payload, with twice the range on internal fuel compared with the F/A-18C Hornet,
achieving much the same goal as the heavier F/A-18E/F Super Hornet.

The F-35 Lightning II is a fifth-generation, single-seat, single-engine stealth multirole
fighter that can perform close air support, tactical bombing, and air defense missions.

The F-35 has three different models:
(1) The F-35A is a conventional takeoff and landing variant.
(2) The F-35B is a short take off and vertical-landing variant.
(3) The F-35C is a carrier-based variant.
A-A Stations (5 and 7):
AIM 120 Slammer: 348 lbs
A-S Stations (8 and 4):
GBU 31: 2125 lbs - ONLY A and C versions! Does not fit into the small -B version bays!!!
GBU 32: 1013 lbs
GBU 12: 1220 lbs
Sidewinder stations (1 and 11)
AIM9X Sidewinder: 382 lbs (pylon 194 lbs + missile188 lbs)
All other extenal stations (2, 3, 9 and 10)
Mount empty pylon: 350 lbs (DEFAULT)
GBU 31 (2125 lbs) + pylon weight (350 lbs) = 2475 lbs
GBU 12 (1220 lbs) + pylon weight (350 lbs) = 1570 lbs
JSOW (1041 lbs) + pylon weight (350 lbs) = 1391 lbs
FUEL TANK (3561 lbs) + pylon weight (350) = 3911 lbs (ONLY STA3 and STA9)
CBU (2x) total weight = 1900lbs
Gunpod station (6)
Missionized Gunpod with 540 rounds = 550 lbs

Similar in size to the A variant, the B
sacrifices some fuel volume to make
room for the vertical flight system.

Takeoffs and landing with vertical
flight systems are by far the riskiest,
and in the end, a decisive factor in

Pressing the “HOOK/STOVL” button in the cockpit
activates the conversion to STOVL mode.

You cannot convert from CTOL-config into STOL-
config when the airspeed is above then 250 Knots.

In STOL-config, you cannot activate the Hover
mode if you are too heavy for VTOL operation (total
weight > 40600 lbs); in this case the HOVER button
of the FCS will be red. You may want to dump fuel
via the FUEL/DUMP command until the total
weight is within the 40600 lbs limit (HOVER button
turns cyan)

In STOL-config, pitch&bank attitude is limited to 30
The STOVL version F-35B uses the Rolls-Royce LiftSystem, patented by Lockheed Martin
and developed and built by Rolls-Royce.
The Lift System is composed of a lift fan, drive shaft, two roll posts and a "Three Bearing
Swivel Module" (3BSM). The 3BSM is a thrust vectoring nozzle which allows the main engine
exhaust to be deflected downward at the tail of the aircraft. The lift fan is near the front of the
aircraft and provides a counterbalancing thrust using two counter-rotating blisks. It is powered
by the engine's low-pressure (LP) turbine via a drive shaft and gearbox. Roll control during slow
flight is achieved by diverting unheated engine bypass air through wing-mounted thrust nozzles
called Roll Posts.

Users can change the loadout (and the appearance) of each model by entering the proper
values as in the Aircraft>Fuel and Payload menu. Load stations are numbered in the same
way as the real F-35 (see figure below). Currently the model supports only a small selection
of the weapons systems that will be available to the F-35 in reality.
Weight values that users should put are as follows:
GBU 31 Loadout
External Gunpod located in
the middle (station 6)
CBU Loadout
Anti-Air Loadout
AIM9X Sidewinders on wingtips
and AIM120 Slammers internal stored.

External Fuel tanks
DO NOT add fuel,
only weight.
Empty Loadout, no pylons
