I can't read the German either but would suspect that a paragraph by paragraph translation through babel-
Would reveal that ONLY THE SEEKER from IRIS-T is being used.
The main missile system is the French 'Polyphem' which in turn is an evolved copy of the U.S. FOG-M.
The reason I suspect this is because the IRIS-T (Infra Red Imagery Sidewinder Tail-controlled), like all such _AAM_, is a supersonic boost-to-coast
weapon which means that:
1. It's Not likely going to reach 15km from low level on anything but a ballistic trajectory and against jet powered ASW systems, it may have
limited pursuit and/or altitude options from a static launch.
2. It Will shear if not burn off any FO tether by simple virtue of it's acceleration rates and TVC.
3. It Will be 'rather difficult' to target by relay if such is actually required.
4. It Won't do a whole helluva lot against even frigate type surface combatants.
This will get you started I think-
I am struggling to comprehend how it is both " autonomous " and
" fibre optic guided , but something could have been lost in translation .
Most I2R seekers are quite capable of autonomous lockon with little or no human intervention or 'slew' it simply requires that you tailor the specie
to which the seeker is most responsive (that which is 'brightest' or 'darkest' on a black hot/white hot display to a human) and then get the
weapon FOV over the general target area. D-Maverick could lock up targets that way with little or no trouble, just by putting the HUD waterline mark
over the general TLE zone.
The problem (with the FOG as well) was always getting the missile into a remote cued area for either seeker or operator to see the target. In this,
the earlier TV guided missiles often ended up being 'flown' all the way into drone UH-1 surrogates and we didn't want to restrict ourselves to only
optical modes in daylight (the program was originally part of the FAADS air defense system to replace Sgt. York in European theaters where the weather
is low-overcast half the time and 'worse' the rest). The later Platinum Silicide seeker proved to be more flexible but cost reduction measures vs.
produceability yields never really provided an affordable guidance system for 'pot shot' random sightings of targets through the soda straw.
These days, GPS and/or an offboard mark (laser) would be used to set the height of the ballistic midcourse phase and probably the slew and graze angle
of the seeker via the digital IMU to more or less open-eyes to the operator with the weapon TLE only off by a few meters, if that. This would then
leave him 'Man In The Loop' empowered to look at the target, confirm it was what he was expecting and move the graticule over to lock it up.
In cruise missiles all of this was automated via DSMAC about 20 years ago of course...
It looks like a cool thing for a sub skipper to have available though, and a nasty shock for some ASW crew busy dropping sonobouys, or worse dipping
sonar,- no where to run when you are hovvering
Indeed, it basically removes the practicality of the lone aerial USW platform on a sheer airframe value + extended mission area approach times, even
for most loloing fixed wing assets.
That said, as we found out in the FOG-M effort, hitting a dynamic target moving across a target field is no easy task by hand and hitting one lined up
with the missile's own flight vector often left you searching for one dark spot against field of other darkspots with little or no (snap down = more
area and better trajectory dynamics) bright horizon or dirt-scaled target popout until VERY close to the terminal intercept.
Myself, the only really interesting element here is the notion that this system is encapsulated in a 'caddy' as you put it. While I would NOT
choose either an FO or a rocket booster, the notion that the weapon can potentially be _sewn_, like a mine is important because it lets the sub layer
it's defenses and employ them while undertaking other missions. Together with the subs native stealth, this theoretically allows you to use
/another/ tether. Or even an acoustic or lidar based LINK to launch from well away from the weapon broach signature and indeed without the
highpressure blow of a conventional torpedo firing (many modern mines are mobile and can 'swim out').
This is much different from say land based air defense systems where there is still a regrettable tendency to site the launch box and it's missile
right atop the active cue/guidance sensor. Limiting the envelope coverage of the first. And the sensor horizon of the emitter (it may also extend
the engagement window and increase vulnerability of the radar to reactive ARM shots).
How ironic that it takes the near total vulnerability of the sub near the surface (or close to a battle group) to create an effective remote-fire
launch system. Now if only they would go to a MALI type airframe and a turbo propulsion system the notion of an 'autonomous hunter' would actually
have some meaning. Lord knows even 'only' a 550 million dollar SSK asset should be worth a few more bucks for the turbine and autonomous search
pattern navigator and you can still use RF to send back an image to whatever antenna you care to stick up out of the activated launch capsule...
