Both aircraft have a VTOL version, using different methods to achieve it. However, that's also the most expensive version which will be built is the smallest numbers. As the customers for VTOL are, so far, only the USMC/RAF/RN this version could be cancelled.

Each aircraft is being built in 3 versions:
1) CTOL version for use from normal airbases. This is for the USAF and most export customers
2) Carriercapable CTOL version. This is basically the same as 1) but with strengthened gear and tailhook for carrier ops. For US Navy and USMC. Potential export customers are currently extremely limited.
3) STOVL version. For use by USMC and Royal Navy and Air Force to replace the AV-8 and Harrier. Potential export customers are current Harrier operators and anyone aspiring to join the club.
Unit price goes up as you go down the list, while performance goes down (a bit) due to increased weight.
