“This award reinforces Tods’ standing as the leading supplier of sonar domes with experience in supporting the world’s most prestigious programmes, including the DDG1000 (USA), P28 (India) and Type 26 (BAE Systems).”

The manufacturing plant will begin operations in early next year, according to the company.
