I haven't see an RfP or contract text, but China has much more ships on offer than 054A, which, at over 4000 tons, is a fairly large ship and possibly too large for the needs of a great many navies that would buy Chinese export ships. And purchases will depend on available budget + extended credit.
There are great offerings such as further developments of F22P (2 variants: Tiger andC28A), and there is also a further development of the C28A itself. On the lower end of the spectrum the multimission frigate. And at the higher end there are the High performance frigate and the 4k ton frigate.
Multimission frigate (1500 ton)
"F22P with VLS for HQ16" (don't know the official name, "Tiger frigate"?)
C28A
Modified C28A with VLS (don't know the official name. Note absense of radar target illuminators > VL SAM is NOT th HQ16 > active radar homing DK-10?)
High performance frigate (HQ16)
4000 ton frigate(DK10?)
As shown, and as I have indicated in another thread some time ago, there are indeed 2 versions of the MANPAD launcher out there, one manned and one unmanned.
Aside from that, you should also realised that the fact there is a person in the missile unit does not preclude an automated slew to cue function. This is e.g. how the optically tracked US Avenger system (Stinger on Humvee) works: the engagement is under control of the turret operator but when hooked up to the FAAD C3I system, the turret automatically slews to the target general direction, placing the target in the gunner's field of view, cued by an external AN/MPQ-64 battlefield air-defence radar.
Don't attempt to twist what I said. The Burmese ships are armed just fine as they are. Equal or better in terms of all weapon systems except the SAM, compare to the four (light) frigates I mentioned. And given a very good close in gun armement, they are still well protected. However, they would be even better with a VL SAM, mainly because this would better against attacks with multiple missiles arriving from different directions simultaneously. But that also applies for F22P and Bangabunhu.
Better range is always nice but note VL Sea Wolf does only 10km versus 50 for ESSM. FL3000N does 6-9km depending on target type. A manpads with 5.5-6km isn't much poorer and does have advantage of easier reloading while at sea, which will be an issue with FL3000N and HQ7/FM90.
