These are three real Jet fighters that actually flew including one projected further development of the 262
included are: -the Me 262 Schwalbe, a twin engine jet fighter
-the Me 163 Komet, a single rocket engine interceptor with low range but high possible speeds
-the He 162 Salamander, a single engined jet interceptor
-the Me 262 HG III, a projected version of the Me 262 that was supposed to be faster
All the jet's are fitted with one basic fuel tank so they should at the least be able to reach over the ocean and even more.
Here you can see them in action:
