   Still looking at a Me-262 B night fighter concept and was wondering if there were any attempts to marry  ZG 1229 Vampir type night vision equipment with the X-4 AMM or with the gun sights?  Tia

ZG 1229 Vampir was an infantry IR set.  Why would they try and fit it to a flying nightfighter?  Its range would be too short to use.  The X-4 was a purely a visual wire-guided missile which you couldn't use at night.  There were no plans to fit it to the Me262 because it's speed (the missile's) was too slow.   They had only carried out trials on Fw190s before the war ended.

As the tech was adapted to work on an armoured vehicle it seems reasonable to project a theoretical application to aircraft.  The tank mounted version had a working range ok 1km with increased power relative to the infantry version.

That was 'cause the tank version mounted a 200w IR search light and for really long range there was a even bigger IR search light on a Sdkfz 251.   There were both active IR - in other words they needed an IR light source which reflected off of objects to enable them to be seen.  That means that you have a nice shiny IR searchlight...

    • Lots of works in my FlickR gallery
There were several "Spanner" devices in Luftwaffe use, an active one, coupled with an IR searchlight, and passive types, but they were only produced in small numbers. There was also the FuG 280 "Kiel Z" from Zeiss, another passive IR target finder. Lead sulfide photocell with amplifier, display on a Braun tube. Range 4 km, weight 42 kg. However, these were IMHO not suited for missile guidance, esp. the passive types - imagine looking at a hot burning tail of a missile and try to make out a target ahead? And probably trying to activel steer the missile at a moving target? While flying an aircraft close enough to take enemy fire? In darkness? Nope. Sounds like a B movie idea to me.  :-\

Added note to what Dizzy just said. If your using an IR sight to track your target at night or in bad weather and you fire a nice rocket powred missile at the target, the plume of your missile exhaust will probably cause your IR sight to flare making it useless. By flare I mean that it will cause the sensitive sight to become overloaded so all you see it a bright return filling your sight and nothing else.
