I've put forward an F22P development on several occasions but folks here don't like it, they insist on Type054A or at the very least that 3700 ton 'high performance rigate' design... as if either is a) affordable and b) a game changer.
Here an F22P development being built for Algeria, called C28A. It features a replacement of the stack/exhaust uptake with waterline exhausting, freeing up space for a different radar set, as well as a Thales Smart S Mk2 radar and CMS. Just putting in Sylver A35 launcher with quadpacked VT1 gives better self-defence coverage relative to F22P, without a need to change much in terms of e.g. missile director. Using Sylver A43 with quadpacked CAMM or equivalent length Mk41 Self defence launcher with quadpacked ESSM would be even better. CAMM would have my vote as it doesn't rely on radar directors or illuminators for missile guidance, only on a 2D or 3D main radar for targeting.
