Dunno, ask your @warrantofficer guy. He thinks the ansar legions will bring a Bangla-Rashtra empire or something very soon.

Transportation of BTR-80s requires thta BD either build a few landing ships of its own or at least buys from others. The link from another forum below states the new procurement of about 50 APCs by the BA.

That was the point of my starting to look at transport options.

When you have mobility options with a platform like the BTR-80/82 - it pays to maximize the mobility, especially across water. In this case I was looking at what the Russian and Chinese (PLA) navies do. Of course the strategic scenarios are entirely different but this is looking at theoretical use only.

Between Evan Gren and the Chinese Type 072A (both 5000 ton class), I'm really impressed by the latter, with the beaching flexibility etc.

However I think that size of landing ship (5000t) has hardly any use under current Bangladesh Army usage scenario, unless the army raises a Marine expeditionary force, which is unlikely at this time.

Smaller LST's are much more appropriate which are usable in a defensive mobility scenario. That's where we need to seriously consider LST's like the DYUGON class. When I spoke about the DYUGON class being advanced, I wasn't kidding. The hull has utilized CAD design and facilities for an Air Cavity Hull Design by incorporating an injected carpet of bubbles around the hull to reduce drag by about 20%. Plus - like I said it uses two of the same ZVEZDA M503/M504 – 56-cylinder turbo-charged four-stroke radial diesel engines used in the OSA class for brute force (5000 HP each) and proven reliability. Our navy (and the Chinese PLA Navy) are already very familiar with this engine since the seventies.

Now - the latest Chinese analog and alternative to the Russian Dyugon class is the relatively unknown Type 074A PLA Navy catamaran LCU. By definition, Catamarans are much faster then mono-hull vessels and this solves a host of issues with a flat-bottomed low-draft boat (such as drag).

What is an LCU (Landing Craft Utility)? Well here's a rather idyllic visual of Dutch and US LCU's ,

Curacao, Netherlands Antilles (June 6, 2006) - Two Landing Craft Utilities (LCU) assigned to Amphibious Craft Unit Two (ACU-2), rehearse storming the beach in Curacao, Netherlands Antilles. ACU-2 is embarked aboard the amphibious assault ship USS Bataan (LHD 5), underway joining military forces from France, Spain, United Kingdom and Venezuela in the Dutch led Joint-Caribe Lion 2006 (J-CL06) exercise. U.S. Navy photo by Photographer's Mate 3rd Class Jeremy L. Grisham.

Some images of the Type 074A PLA Navy catamaran LCU (these are almost identical to the US design for similar applications - US LCU 1600):

The last picture shows two variants of the catamaran LCU (types 074A and 074B). About 550-600 tons. 13 or 14 crew. RANGE about a thousand miles. And probably a lot cheaper to build than the DYUGON class.

Here's the trusty and rusty US LCU 1600 - the poster boy of what a utility boat is.

They are thinking about an affordable replacement. I think letting Bangladesh yards build them could make them quite affordable to start with but the US Military doesn't do that sort of thing.

One replacement (although expensive) for this LCU is the French L-CAT. IMHO - this is way overkill for the intended purpose, Chinese 074A/B and US Navy LCU 1600 are great designs for Bangladesh Army applications.

Let some fantasize a bit - what's the harm?

Kumbhir-class L-21 and L-22 LSTs (in the middle), and L-32, L-34 LCUs of the Indian Navy beached during an amphibious landing. The Kumbhir class was built at the Gdansk Shipyards in Poland .

Here are two more prototypes in use by Turkey and Australia, The Tuzla class (16 built by Dearsan Shipyards in Turkey) and Armidale Class, respectively. These are similar to the IPV/OPV's DEW is building in Narayanganj (4 + 4 of two types).

Meanwhile Turkey has also introduced new larger LCT's for their own use.

Characteristics:
Displacement: 1155 tons full load
Dimensions: 79,85 x 11.7 x 2.5 meters
Speed, Range: 20 knots, 400 miles at 16 kts.
Crew: 22

Weapons:
Guns: 2 x 25mm; 2 x 12,7mm

Sensors:
Radars: Navigation
Other: ASELFLIR 300D

Comments:
These LCT’s can carry 250 troops, or 320 tons of cargo.

Bangladesh Navy warships leave for India, SL

DHAKA: Two warships of Bangladesh Navy have left Chittagong naval jetty on Sunday (September 18) for a goodwill visit to India and Sri Lanka.

The visit of warships ‘Somudra Joy’ and ‘Somudra Avijan’ will be a gesture of fostering goodwill contribution to the deepening friendship of Bangladesh with the two countries.

Assistant chief of naval staff (personnel) Rear Admiral M Shaheen Iqbal, Chittagong naval region commander Rear Admiral Akhtar Habib, naval officers, mariners and their family members, among others, attended the ceremony at the jetty to see the delegation off.

As part of the training program, the 511-member naval delegation will stay at Port Blair from September 21 to 25 and in Colombo Port from September 29 to October 4, said a navy press release.

According to the release, the visits aim to train the new officials and cadets as well as strengthen the existing friendly relations between the two countries.

Captain M Humayun Kabir will be the commanding officer of the ship ‘Somudra Joy’ and Captain M Qamrul Haque Chowdhury of ‘Somudra Avijan’.

The ships will return on October 9, the release added.

Didn't Bangladesh already started making landing crafts?

We do...but 95% are like this!

Small, Medium and Large all have their specific uses. I remember non-Bangladeshis making fun of the mini-LCT's a few years back but a military person knows what they are used for.

Small LCT are needed for point-source force-multiplier situations where more than a couple of tanks would be overkill. And they're perfect for constricted low-draft canal environments where a larger LCT would have trouble maneuvering.

Medium and Large LCT's are for conventional LCT use - non-amphibian tank movements en masse where a few companies of troops may be involved.

Now for a pop-quiz. Where is this yard in Bangladesh and which builds are they working on?

well .. there is many difference between corvette and Large patrol craft.. Durjoy Class LPC is just LPC-M which has 650 tons and 64m length.. no offence..!!

Well....agreed. No offence taken. However BN has a history of modernizing armament in steps and not at one go.

Larger ships have three layers of defense, long/medium/short distance countermeasures coupled with electronics suites. The first two are missiles and the third is usually as CIWS. Offensive is usually missiles like C-704/802.

Smaller ships like Durjoy class LPC-M omit the long distance missile defence but have most other countermeasures including electronic.

1. How is having C-704's not having offence?
2. What is the Myanma Mavy naval counterpart (same size and displacement) and how is it equipped?

Great effort, now they need to start making them biigger

They already make the Shakti Shanchar class 66m LCT.

Plus they have quite a few large foreign-made LCU's of 500+ ton class as well. Total number of service-worthy LCU/LCT's are around 19 I believe.

Can this LCT operate in high sea or designed for inland river ferrying.

LOL... just misunderstanding..!! i 'm not talking ur ships has no teeth... just want to say i just point out what is LPC and corvette and not talking bad.. nothing more..!!

may be FAC 491.. but still smaller than ur ships.. 491 is just 49m and 550tons..

This is my backyard and they are making aircraft carriers...
Or maybe Khulna ShipYard making Padma Class OPVs...

Why do you people put numbers instead of names on ships? Doesn't look right..
BTW,they look like Azmat Class of PN
