Why few STOVL fighters reach operational service

Vertical and short takeoff fighters impose difficult engineering costs while dispersed bases and short conventional runs can solve many of the same operational problems.

Question

Why have so few vertical or short takeoff fighters entered operational service?

Short answer

They are technically difficult and often unnecessary when rough-field aircraft, road bases, or short conventional takeoffs can meet the mission more cheaply.

Notes

Operational STOVL fighters are rare because the propulsion and control problem is difficult while the number required may not justify multiple national programs. Sweden and Finland show that rough-field aircraft and prepared road bases can provide dispersal without full vertical landing. Short-takeoff utility aircraft can also perform roles such as carrier delivery from a large deck without catapults or tilting jets. STOVL becomes worthwhile only when power density and mission need overcome the penalties that otherwise make simpler alternatives more efficient.
