| Created by the OKB as the Zh to meet a 1945 requirement
for a rocket-propelled target defence fighter, the
I-270 was based broadly on the Messerschmitt Me 263, but was of a less radical configuration, featuring
a straight wing and conventional horizontal tail.
Adopting an ejection seat for the first time in a Soviet
fighter and having a wing of near-laminar flow profile,
the first of two prototypes was towed into the air
behind a Tu-2 - with ballast replacing the rocket motor
- in December 1946. Only the second prototype was to
be fitted with the rocket motor. This, the RD-2M-3V developed
by L Dushkin and V Glushko, was a bi-propellant
dual-chamber unit affording a total thrust of
1450kg of which the cruise chamber contributed
400kg. The cabin was pressurised and
proposed armament comprised two 23mm cannon and
eight RS-82 rockets. The second prototype flew under
power early in 1947, but was written off as a result of a
landing crash while being flown by an NII VVS pilot. Shortly afterwards, the first prototype was damaged in
a belly landing and was not repaired.

They are similar looking ..heck yeah. But 100%? Not even if you squint. reply | | Robert, e-mail, 03.04.2012 02:57 To say that this is a 100% of the Me-263 makes me think you're blind.

| | Kent Meyer, e-mail, 06.12.2006 06:40 I'm working on a kit of the I-270. I have two questions: (1) what color would the seat belts have been; and (2) did the radio antenna post run through the rear of the canopy glass or was it set to the side of the rear canopy (like a Yak 15 and other aircraft of that era)?
Thank you! reply |

Do you have any comments?

I'm really surprised that after all these years, no one has responded to your question. The answer to your question is that the antenna post, as shown in the 3D images, was mounted to the rear section of the canopy.
