This one is a dead giveaway; but if you don't know the answer, it makes for some interesting history. Thanks; Ernie P.

What was the first fighter aircraft to fly using liquid rocket power?

Hint: Read the question.

ORIGINAL: Ram-bro

the Japanese Baka

ORIGINAL: wingspar

Alright then the Bereznyak-Isayev BI-1

Or is that a different plane than the one Dave said?

ORIGINAL: dvs1

Was it the Bachem BA 349 Natter?

Edit:

Disregard that answer. I cant remember the name of the plane but it was flown and desinged by Alexander Lippisch way before the war started.
Remember seeing it on the Military channel a while back. It was the forerunner to planes like the ME-163.
I want to say it was the Ente or something like that

Ernie, I was just eliminating choices fo the fellas.....

ORIGINAL: Ram-bro

give us another hint, was it rocket assist or strictly rocket power?

ORIGINAL: P-40K-5

really.

the Messerschmitt Me-163 Komet actually flew in combat. wiki isn't the bible.
