“they are not going to install the major sonar systems, relying on the single embarked helo as I understand it.”
In bad weather when the helo can’t fly the ship will be blind to submarine threat?
Until they allocate the funds and install the sonar, the ship, outside of its own helo, will have to rely on other vessels in its task force. IMHO, foolish liberal mind set to send such an expensive capital vessel out with such deficincies.
