Just a side point.

STM will also take part in the PN’s new Miniature Submarine Program.
As per the PN’s request, STM had studied the feasibility of upgrading the Cosmos MG110 (SX756/W) mini-submarines, which were bought in the 1980s to replace the SX404 mini-submarines, but both sides then concluded that this was not an affordable route.
The PN Submarine Force took pride in operating 3 X-Craft (Cosmos MG110s), which were transferred to the Squadron in March 2005 from the Special Service Group Navy (SSG[N]). This has enhanced the number of sub-surface units to 8 instead of 5 having been in operation prior March 2005.
STM, later on put a proposal on the table covering the joint development and marketing of a new generation mini-submarine intended for special forces operations (such as insertions and extractions of SEAL Teams) in littoral waters not only to meet the PN’s (to replace aging Cosmos MG110 in the inventory) but also the Turkish Navy’s (considered TKMS Type 200 and Type 300 mini-sub designs in the past) and other potential customers (Azerbaijan is said to have already declared its interest according to our sources) requirements.
So, STM has designed a new type of mini-submarine platform for the PN from scratch and STM General Manager Murat IKINCI presented a scaled model of this mini-submarine to Pakistan’s Ministry of Defence Production during the signing ceremony for the second contract amendment held in Rawalpindi, Pakistan.
It seems that scaled mock-up is this:
