You must have missed this:
MBDA presents the SPIMM (Self-Protection Integrated Mistral Module), an all-in-one air defence module based on the SIMBAD-RC system and designed to equip ships of all types.

Here are the space and weight details:
No I did not but I was not clear either ... sorry my bad. A couple of things:
1. IR sensors as a sole detection method offers much less in detection capability than the Mk 15 CIWS you are looking to replace. The combination of scan and track radar, internal fire control arrangements (it does not require two operators in the cab) and optics are better that an IR sensor alone. If the vessel has a capable air search radar you would want to be using that as well given this will generally be located high in the ship and above the module and IR sensor.
2. Seven tonnes is not a massive weight and most cargo vessel could accommodate this pretty easily ....
in locations where the deck loading can take it. Accommodation decks are generally not designed for high point loads (this thing has container fittings for securing so the load is distributed on four points each about 10 inches by 10 inches). So real estate is going to be your problem as I suspect this will end up in one of your container spaces on deck (which means) it may be close to the main deck rather than on the higher decks. If you want to put it higher you are going to have to modify the structure (even if that is only the fit securing sockets).
3. I cannot see such a system being fitted to the RNZN FFH's given they have seaceptor and the Mk15. As a result you will be buying different system for your auxillaries and using a different missile or gun system. The bean counters hate multiple systems with associated support costs.
The ethos behind this offering really is a last ditch system that I can see being used for ships taken up from trade (STUFT) for a particular operation.
