INVESTIGATIONS IN GERMANY
TANK ARMAMENT RESEARCH,
MINISTRY OF SUPPLY
(B.I.O.S. Trips 927(a), 957 and 1565)
Features of outstanding interest discovered during the investigations were: -
(a) a new periscopic gun-sight (p.29), which was intended to be universal for tank, anti-tank and flak guns,
(b) a system for gyro-stabilisation of the sight-line (p.25) for use in tanks. Prototypes of this equipment had given very promising results.
Little of interest was learned on other matters. The Germans appear to be less advanced than we are in solving the problem of obscuration. No reliable information was obtained on German Army tank-gunnery range methods.
- II OBJECT OF INVESTIGATIONS
The investigations were made to enquire into German developments of equipment and methods pertaining to the righting aspects of tanks and self-propelled guns. In particular, information was sought concerning research work being pursued along the lines of that at the Tank Armament Research Establishment of the Ministry of Supply, with a view to discovering new ideas and intended developments of new equipment. A detailed list of the subjects on which information was to be sought, drawn up before the personnel left England, is given in Appendix I.
As the subjects listed in Appendix 1 did not fall naturally into any one of the B.I.O.S. Groups, the investigations were in some measure exploratory. Travelling arrangements were made by Group 5 ( A & B Vehicles), but technical assistance was provided both in England And in Germany mainly by Group 2 (Armaments). A.F.V. (Tech) and GSI (Tech) at HQ, B.A.0.R. were also contacted in Germany.
- III ITINERARY
- The targets visited are listed in Appendix II.
- IV PRESENTATION OF REPORT
This report is, in the main, a non-critical account of the information given by the various Germans who were interrogated. It is intended to issue in due-course further reports dealing in more detail with specific matters, usually after trials have been done with German equipment. Much of the information recorded has no doubt been reported previously by other investigators, and some is of no direct interest to Tank Armament Research; such is included here for the sake of completeness. Many of the items listed in Appendix I were not covered by the present investigations, mainly because of lack of time and opportunity. Thus many gaps remain to be filled by Tank Armament Research. It is hoped in many instances to obtain the required information from other investigators. For convenience of presentation the report on the investigation is divided into the following Sections, which do not follow precisely those listed in Appendix I.
- Section A Policy regarding the Fighting Equipment of Tanks and S.P. Guns.
- Section B The Heereswaffenamt.
- Section C Accuracy of Tank Guns.
- Section D Artillery Range methods and Equipment.
- Section E Methods of Improving Observation of Fall of Shot.
- Section P Gyro-stabilisation of Gun and Sight-line.
- Section G Sighting Equipment and Methods of Fire Control.
- Section H Physiological optics and Optical Constants.
- Section J General Physics.
- Section K Miscellaneous Items,
Appendix III contains a list of the reports evacuated from Germany, while Appendix IV enumerates the items of equipment that 'T' Force has been requested to send back to England.
