they are different systems
So dircm is just built in and circm is a simpler verison mounted on pilons?
Thats one thing thats different yeah. DAIRCM is also newer and smart(has a computer)
im fairly sure circm is daircm(its not apparently only leonardo has a design thats in service rn of daircm). there are some figures on the laser wattage going on the internet and its pretty high, but is there even a difference betwen LDIRCM and DAIRCM? like as far as i know the term LDIRCM isnt used outside of WT
there wouldnt be a distinction between built in the airframe and installable
Please stay on topic.
Not exactly, they are functionally similar systems that use different mounting solutions.
The CIRCM is mounted to the Wingtip station, which prevents other systems (such as a Sidewinder, ATAS or other sensors / uplinks from being mounted).
The DAIRCM, replaces the AAR-47 UV MAWS in their cheek / aft blister(s), and still provides equivalent functionality for the Countermeasure suite.
