M4A3 Sherman Calliope - T-34 rocket launcher - case report

       Gents: an American tale, now...The story of a tank with bad attitude, with a devastating firepower, but still unpopular among their crews: Sherman Calliope.

History:
      The Rocket Launcher T34 (Calliope) was a tank-mounted multiple rocket launcher used by the United States Army during World War II. The launcher was placed atop the Medium Tank M4, and fired a barrage of 4.5 in (114 mm) M8 rockets from 60 launch tubes. It was developed in 1943.
      The US Navy pioneered the use of rockets to supplement conventional artillery since they could be fired from landing craft and other small vessels that could not carry conventional guns.    
    In 1943-44, the US Army began examining the use of these rockets as a means to supplement tank guns. The first efforts as mentioned above involved the use of 7.2 inch demolition rockets from the T40 launcher for breaching seawalls during amphibious landings. This was later standardized as the M17 Whiz-Bang launcher.

     This device was never very popular since its proximity to the turret roof created problems for the crew entering or escaping from the vehicle. and the rockets had a relatively short range.

     Being intended for firing from only a hundred meters with a maximum range of barely a thousand meters. After being rejected for use on D-Day in Normandy, and after being used with little success during Operation Anvil in southern France,  the army decided to hand over the surviving launchers to tank battalions in the Italian theater for possible use in the artillery role. 
      The 752nd and 760th Tank Battalions each converted a tank platoon with four T40 Whiz-Bang launchers in mid-August 1944. These rocket platoons did not serve with their parent units, but were instead transferred to the 755th and 757th Tank Battalions for operations along the Gothic line. They were used in very small numbers and had modest results. In December 1944, the 525th Ordnance Battalion converted eight T40 launchers by replacing the 7.2 inch demolition rockets with the longer-range 4.5 inch aircraft rocket launcher. They served with the 752nd and 760th Tank Battalions and saw combat starting in March 1945.

      The US Army had already developed a launcher for the 4.5 inch rocket as the T34, better known by its nickname as the "Calliope".  It adopts its name from the musical instrument "Calliope", also known as the steam organ, which had similar lined pipes.

     The original plan was to use these for obstacle breaching on D-Day, but this was rejected out of hand since it was felt that the high mounting of the launcher on the M4 tank would make it unstable in landing craft.

     After D-Day, the 743rd Tank Battalion had 30 Calliope launchers installed for a planned attack by the 30th Infantry Division in December 1944. However, the German attack in the Ardennes pre-empted this operation and the launchers were discarded without being used.
Changing the tubes...
      The T34 was more extensively deployed in early 1945, and was used in small numbers at various times by the 2nd. 4th, 6th, 12th, and 14th Armored Divisions and by the 712th, 753rd, and 781 st Tank Battalions. In general, the launchers were unpopular with tank commanders who felt that the artillery mission should be performed by artillery units and not tank units.

The kit:
      For this project, I used an old Italeri M4A3 Calliope:
Italeri kit n. 288 M4A3 Sherman Calliope
       Let's go...Correcting the suspensions: Dragon bogies and wheels; Italeri arms and drive sprocket and track (with duckbills) from Tamiya...
Multimedia kit...


Suspensions done...I love my spare parts box !!!
The Dragon bogies, with casting marks...cool !!!
The Calliope tubes...
and the Italeri turret

         Uops... I almost forget the reinforcement in the turret's cheek armour.
Plasticard and putty to do the turret's cheek.

        While the cheek dry, we will do the rear rack, characteristic of these Calliope Shermies ...
