Britain funded Spearfish's development and brought the weapon together, while several allied nations contributed technology or work. That makes it a possible basis for a common NATO torpedo even though it remains a Royal Navy system. The criticism is that successful technical cooperation has not translated into wider adoption. National politics are identified as the obstacle, despite the number of allies already involved.
