MASS was formed in 1983 to supply the UK defence industry with mathematical and associated scientific services, which gave the company its name. Founded by four partners Malcolm Lowes, Fred Pew, John Cresswell and Roger Millington, MASS has grown into one of the UK's most successful defence technology companies.
Throughout the 1980s MASS grew steadily, and expanded from offering pure consultancy to developing services and solutions. The firm also developed capabilities in a diversity of technical areas such as analysis, mathematic modelling, guided weapon performance analysis, design, development of bespoke systems and RF test and evaluation.
Due to investment by a venture capital company, followed by a majority holding being acquired by Silicon Valley Group in 1993, MASS saw a period of significant growth. Over the next decade its turnover increased from less than £1 million to almost £13 million, due to winning prestigious managed IT contracts including highly secure MOD business. MASS also developed skills in real-time software, electronics systems design, development and low volume manufacturing, particularly for aerospace.
