Executive Summary vi Aardvark Mine Clear Ltd have been designing and producing mechanical mine clearance equipment for the last 17 years, supplying 25 different countries. The latest version of the Aardvark Flail, the Mark IV, came to the trial with an extensive depth of knowledge and experience behind its design. The testing and evaluation of the upgraded Mk IV Aardvark was carried out by DERA on behalf of DFID (The Department For International Development). The tests were carried out at DERA’s Bagshot test track in the U.K. and were designed to test the potential of the new version of the Aardvark flail to clear antitank mines from roads, tracks and cross-country. Testing was done under the headings of Transportability, Mobility and Performance. No Survivability tests (Live Ordnance Encounter) were carried out since the Royal Netherlands Army Ammunition Branch had already carried out survival tests¹ on the Mk IV Aardvark. During the trial the Aardvark Mk IV proved to be a well thought out and engineered machine. It proved to be very manoeuvrable for a vehicle of its size. It has the ability to be stripped down to make it air-portable and it fits onto the back of a large low-loader truck making it easily transportable. Aardvark Mk IV showed a great ability as both a brush and vegetation clearer and a mine clearance device with the capability to reduce medium to heavy density foliage to fine mulch. In the limited tests carried out, the Mk IV cleared all the surrogate model mines in its path. This piece of equipment would be a valuable asset when used in the right environment and under appropriate circumstances. One characteristic of flails such as Aardvark is the amount of dust and debris that is thrown out during the clearance operation, this debris could contain disrupted mine parts and deactivated mines.
