the kriegsmarine and the hs 297 fohn

[sgeorges4]

what would the kriegsmarine do with them? Put them on uboot? (I readed that at first it was going to be for the kriegsmarine ,but they got use by the heer)

Wikiwand - Henschel Hs 297

The Henschel Hs 297 Föhn or 7.3 cm Raketen Sprenggranate was a small German surface-to-air rocket of the Second World War. The associated multiple rocket launcher was known as the 7.3 cm Föhn-Gerät.

Protect destroyers? River boats? Defending installations?

Without proximity fuses, they are not of much use. The firing range is very limited, the reload speed is low. Its main effect would probably be psychological - to confuse Allied pilots, and force them to break the attack.

Put them on uboot?

Maybe, as an attempt to give u-boat some more time to crash-dive and escape air attack. But it would probably be more or less useless: in 1943, the USN and RN patrol bombers already have Mark 24 FIDO acoustic torpedo, so crash-diving was not a salvation for u-boat anymore. Most likely, those rockets were to be installed on some u-boats without any real effect, after which Kriegsmarine would lose any interest in them.

Perhaps based on WW1 experience with the Flaming Onions?

Afaik the Kriegsmarine wanted to use the Föhn for use as an aa weapon to keep the allied longe range airplanes at distance. Later the KM realised that this was not a good idea and intended it to protect their fast boats. But Föhn was an utter failure and was not on the production list for the year 1945. So it may seem that use of the Föhn-Werfer would even weaken the aa capability of an late war S-Boot, but with the latest 2cm Flakvierling 38/43 F with the AEG FMG 45 "Rettin" (at the rear), a 3cm Flak M44 at the front and a Föhn battery in the middle it was well armed.

Foehn was never designated as the Hs 297 and had nothing to do with Henschel.
Foehn launchers of the Kriegsmarine were protecting naval bases already in mid 1944, e.g. IJmuiden.

Does the aft 20mm vierling mounting have a radar between the mounts?

ohh so this is like a GUNAR? or those combined radar and gun mounts of the 40mm Bofors like the Hazemeyer and STAAG mountings?

Though not in the same class with regards to the calibre, the Japanese 5 inch rocket launcher, is said to have been relatively succesful, although it isn't credited with a single kill (Layman/Jenkins in "The Hybrid Warship".)
Quite a number of smoke trails rising up to a pilot, who isn't a Kamikaze, might well
be frithening, especially as most (all ?) such weapons were fitted with a "Selbstzerleger" (selfdestructor), which made it go boom at the end of its
powered flight. Problem may rather have been reloading, which without doubt
was more difficult and lengthy, than for a 20mm quad. So, maybe after throwing
the first attacker off its aim, the second one was left undisturbed.
