PNS Azmat Class - Fast Attack Missile Craft | Updates & Discussions.

All said and done.

Apart from Denmark[and the USN's LCS] , no other nation [which operates any OPV] can up arm the vessel during a war. Untill and unless a war will last more than a week.

You see their [Denmark's ] StanFex Module System is a wonderful thing.

Well, not entirely correct. E.g. RN Castle class OPVs (now passed on to Bangladesh) were designed keeping in mind that they would be uparmed in wartime. This is exactly what BN did on receipt of the ships: it added a Chinese 76mm (rather than the originally intended Oto 76mm) and C-701 AShM (rather than e.g. Exocet or Harpoon). I would bet they can mount 2 triple torpedo tubes and support an ASW helo. I'm sure that, in general, modern OPVs are more geared to this than older generation ships used to be.

The questions here
WOULD IT TAKE YARD WORK (i.e. structural change, welding/cutting, etc)
HOW LONG WOULD IT TAKE? (how readily available are weapons/sensors to be added, and how long to install > plug-and-play into an existing CDS or to be newly installed/integrated)
MEKO ships should have an advantage here.
Stanflex is exceptional in this respect, but relatively expensive (you have to invest in having more modules than all your ships can mount together at one point in time).

Will this ASW system good to be installed on our FACs or littoral ASW assets as it may be able to provide some protection against AShMs too.

F22p has 12 rdc32 anti sub rocket system 34 kg each which can fire similar weapons at longer range 1200-1600 meters plus cy series anti sub rocket assisted torpedo instead of c803 or combination of asrock plus anti ship which are much longer range

Keep in mind this was designed for use in the Baltic, which is relatively rocky and shallow, which can be challenging for ASW torpedo use. I don't see how it has anything to offer in terms of protection against anti-ship missiles: pls elaborate.

The Elma ASW-600 system is a lightweight multibarrel grenade launcher for use against underwater targets.

It can deploy Chef or Flare too.

Will this really effective and good for possible ships from Turkey?

i assume the azmat ship use codad propulsion, how many diesel engines does it have and what make/model are they?

Isn't CODAG more suitable for FACs. With the gas engine providing more speed and Sprint than what Diesel engine can?

yes it is as the diesel engine providing power for cruise speeds and the turbines for high speed.
i highly doubt the azmat has gas turbines, do note just becasue it does not have a turbine engine does not mean its not fast.

This link here says that Azmat class has four diesel engines. Don't know how much reliable is it.

I like this: flexible and stealthy launching system. Drawbacks: possible a bit large and heavy. Could fit single unit on a smaller ship, provided if put at good location e.g. atop hangar roof (but this is prime position also for e.g. Phalanx or RAM system)

four diesel engines driving four fixed pitch propellers (FPPs) through a pair of two propulsion shafts

This ship is propelled by 04 Diesel Engines, 04 Propulsion Shafts with Fixed Pitch Propellers.

I see at least 3 in pic below (2 on each side of keel would be logical)

https://defence.pk/pdf/threads/pns-azmat-class-fast-attack-missile-craft-updates-discussions.130815/

Although there is little info on the engines themselves, they are possible MTU engines or Chinese licence built versions thereof. (Would make sense logistically: Jurrat and Jalalat classes already use 2x 2500hp 4-stroke MTU diesels. Four of these would give a total power of 10k hp, which is more than e.g. the 8.8k hp of the 430t Type 037 Hainan class boats of China, that can make 30.5kn and have a range of 2000nmi at 14kn).

If so, this suggests MTU 12V 4000 M71 or M74, or MTU 16V 2000 M93, M94 M96 or 96L

Gasturbine, while giving high HP output, is less fuel efficient than diesel (i.e. cuts range). Hence traditionally often 4 big diesels on FACs. It is up to the navy in question which trade-off they make in terms of emphasis on high top speed or on range.

Yes. Even I can see four propellers. See the blades of fourth one visible. Clearly.

Understood that the Navy wants better range from Azmat class hence no gas turbine and only diesel. Maybe for speed they are looking at type 22 or FAC 55. Whichever gets selected.

Just to be clear, Azmat class isn't slow (top speed: 30 knots i.e. 56 km/h) and her range is approximately 1,000 nmi (1,900 km). For comparison:

Type 143A Gepard class (Germany)
Displacement: 390 tn
Propulsion: 4 × diesel engines, totalling 13,235 kW (17,748 hp)
Speed: 40 knots (74 km/h)

Kılıç class (Turkey)
Displacement: 552 tn
Propulsion: 4 × MTU diesel engines 15,120 bhp (11.27 MW) on 4 shafts (likely MTU 16V956TB91)
Speed: 40 knots (74 km/h)
Range: 1,050 nmi (1,940 km) at 30 kn (56 km/h)
(enlarged design, with roots in Gepard class, first of class built in Germany by Lurssen)

French La Combattante is similar to Gepard and uses 4 MTU 20V 538 TB92 diesels; 18,000 bhp(m) (12.54 MW) sustained; 4 shafts (P 20-23)

• Range (nmi): 700 at 32 kn; 2,000 at 15 kn
• Speed (knots):36.5 kn

Is it not possible to add more of azmat class but to modify some of them for anti submarine duties near to the coast with modifications made in all the azmat class for short to medium range air defence so that they can defend themselves from air threats?
Thanks

By this way we would be able to add numbers for more coverage and our ships would not be an easy target.
