:::The IP claims that the guns aboard the ships (as shown in photographs) do not correspond with the data in Jane's. The cited edition was published before the ships entered service...maybe there was an armament change during construction? There's already one source giving a different main armament (the Age's 30 mm vs Jane's twin 37 mm) Either way, a post-commissioning source detailing the ships' armament is required, to prove if Jane's or the IP and the Age is correct.
