Apparently the Lightning F6 carried 1,200 gallons of fuel but consumed 200 gallons per minute on full reheat. That is what I was told donkey's years back. It may be true, it may be fanciful. The missiles it carried had a range of just three miles. With Fire Streaks you had to be behind the target, with Red Tops you could fire head on. Don't forget though it had two 30mm cannon. I'm guessing though that there wouldn't have been much time to dogfight with six minutes worth of fuel..?
