Collaborative Technical Programme 2 of WEAG (IEPG) Technical Area 25 (CTP 25;2) was set up in 1989 to investigate pressable explosives and their associated filling technology for "Pressed Shaped Charges". The participating Nations were the United Kingdom, Netherlands, Norway, Spain and Portugal. It has proved to be a highly successful programme, representing true European collaboration, rather than just an information exchange. The programme dealt with the formulation, processing and characterisation of pressable explosives and culminated in a comprehensive shaped charge firing programme. All Nations were able to learn from each other and have benefited from a far more comprehensive programme of work than could have been financed by one Nation alone.
