One of the reasons that the F-16 works so well in combat is that it's a
small fighter. Making the nose larger than 24 inches would mean the
whole fuselage would have to grow. An F-16 coming in on the deck should
be a very frightening thing in an Air to Air confrontation. In the late
70s, Bitburg and Hahn played war games against the Navy. F-15/16 V
F-14. It went down like this. The F-15 played a long ranged Radar Game
(the F-14 was forbidden to use it's Pheonix). The F-16 dropped to the
deck and charge hard. With the F-14s radar, the F-15 was at a
disadvantage. But it bought time. If done properly, the F-16 could
close before detection because of size. And the 16 is more stealthy (by
accident) than the 15. When the 14 picked up the 16, he had some hard
choices. He generally would fire on the 15 and setup to intercept the
15. The 14 would have it's wings back. Just before the 16 closed, the
14 swung it's wings forward. For one turn, the 14 had the energy to
turn inside the 16. If the 15 survived the missiles he would close
fast. If the 16 survived the first attack from the 14, it was game on.
The 15 did not always survive the missile attack and the 16 did not
always survive the first 14 turn.
The 16s size is it's advantage over birds like the Mig-29 and even the F-18.
