I read somewhere that the Luftwaffe was developing a basic type of IRST for night fighters in WW2. Royzee 18:23, 22 February 2007 (UTC) Feb 20 07

You're thinking of "Spanner", it was just IR, not IRST. It was basically a night sight that stuck through the canopy and let the pilot take quick looks while trying to fly. They fitted it to early night fighters, and it proved to be basically useless. Actually pretty much everyone was trying this in the 30's, the Navy was using them in the US, and there was a Cambridge-led program in the UK too. Maury 00:02, 23 February 2007 (UTC)

Just thinking that given the new information that has come to light about the Russian Mig-35 OLS that there should be a major update to this section. The OLS is a whole new generation of IRST systems, providing 360 degree coverage, alerting the pilot of missile launches and heading and giving range finding at a massive 15km. Its that large an advancement it warrants an article pointing out that this system in the era of stealth aircraft may even make radars redundant. According to some rudimentary mathemetics you can determine that this system can fire on aircraft such as the F-22A at greater ranges then the best Russian radars.
