LHD have giraffe radar already. 9LV I believe is integrated with CAMM. Might be a better missile system for the LHDs. Being cold launch, much lighter and much more compact. A 3 Cell launcher is very compact and can quad pack CAMM in each 3 cell giving 12 shots with 3 launching concurrently at a time. It can also launch Nulka or RAM block2. Its like 4m tall and very narrow (<1m?). As a mop up weapon, ideal.
Cold launch means much safer around people, radar, sensors, aircraft, etc. Way less desk space than Phalanx or seaRAM, and way lighter.
With Canada, UK and NZ using CAMM, maybe worth another look as strictly a CIWS. Could be mounted up high.
Could be ideal to augment with phalanx mounts.
Looking back it looks like the Phalanx mounts were announced in 2016 and expected to happen in 2018.. So 9 years later.. Not much word about it.
