China is ahead in this case

We can modify our current and future LPD ramp door with longer and stronger ramp door that extends all the way to the water.

 

[Gary]

Even with civillian RoRoship?

We can modify our current and future LPD ramp door with longer and stronger ramp door that extends all the way to the water.

All 'Civilian' ferries in China built in the 2010's and after has military sealift capability in mind. Something that we could copy. CMIIW after China and Japan, we're like the largest ferry operator in Asia.

Government could kickstart mass national shipbuilding industry replacing our many second hand Ro-Ro ferries using local ships built within a specific requirement that those design has military compatibility in mind. In peacetime good for inter-island transport, in war good for logistics and material movements.

Not to mention, isn't Ro-Ro's rampdoor's job is to do that on a daily basis? Now Idk the details, but a loaded Mitsubishi Canter would weigh more than a BMP-3, would it not?

 

[NEKO]

Yes but it will connect to the pier/ land, but how about a ramp door that is extended all the way to the water?

 

[Ravager]

The only viable option without endangering the crew within zaha/AAV would be an elevated floor .... Without that , the ramp angle would be too steep it creates a lot of more trouble than it's worth

# 1 example ... How much traction it would required for a fully loaded AAV to board up into the ship during a wet sea state 3 ( minimum !! ) and 19° angle of slope ??

hmm part 4 of Nagapasa - Chang Bogo - Type 209 1400 class funfact

10. The screen table you see here

Is Navigation Command Table, provided by Anschütz GMBH

11. The Evolution
The Korean Chang Bogo I (Type 209 1200) is bought in late 90's with license built and modification, but still retain the orginal 1200 ton dimension, 56 meters

* The flat deck above the waterline doesn't have any specific name, and according to some source, it just called as "upper casing"

** The upper casing hold some tanks, piping, equipment storage, and electronic stuff, as shown here

and also here, the Type 212A German Navy

The ID Navy Chang Bogo is different, the hull is streched to 61-62meter, again, to accomodate more sophisticated equipment (both mechanical and electrical) and better storage.

While Nagapasa Class is in subclass of Type 209 1400ton. It is notably different from the same 1400ton class the original manufacturer built. The HDW (now owned by Thyssenkrupp Marine system) built has adopt some of the newer and more aerodynamic approach, especially the sail design, now is much bigger and wider, so there is no little pathway connecting from the forward to the stern

* i had to adjust the upper picture by reversing it so that it poses in similar direction with the lower one

**this comparison is Nagapasa class with newer Eqyptian Type 209 Mod1400 TKMS

As you can see, the Nagapasa class has still retain the original sail design from 1200 ton, it is proved with the same sail door position

But the TKMS built has the door on front side of the sail and on the rear right side, just like the Type 212 and 214

Another thing is the TKMS sail tower is slightly a little bit on forward position compared to Nagapasa,

this may not give any different in performance, but only fitting to the design of control room, as we understand, the control room is very cramped in space and utilized in very efficient way in placing such equipment, it is possible that if the periscope is positioned a little bit forward according to the arangement of control room (remember that the periscope is the only "pipe" that penetrate through the hull upwards to the conning tower)

12. Type 209 Variation
I will only talk about 2 different species of this series.

A. Indian Navy Type 209 1500ton Shishumar class.

Because the Type 209 design is highly customisable, (because it's very basic design of modern submarine). The Indian Navy take it brutally different, they placed an escape pod

The literature said that the escape pod could accomodate up to 50 personnel with 8 hours of oxygen supply, and after seeing the picture of "small" ball shaped pod, i don't believe it, until i saw this

you can count it yourself, and multiple it by 2 since it has 2 level.

Yea it's crazy so many personnel could be accomodated in to that little sphere life-saving pod

B. The Argentine Navy 1700ton class Ara San Juan

The design is different, the hull diametre is larger than the original (6.3 meter diametre to 7.3metre) so that it could accomodate double level (instead if single level on original type)

But it is unfortunate to this very ship, The Ara San Juan sunk on the Atlantic Ocean on 15 November 2017 in the depth of 900 meters


That's it guys, the funfact series of Nagapasa class has come to an end. If you knew something we didn't, as long as it's not life-threatening-classified-information, just share it here guys. Im sure the member here enjoyed this thread.

Bonus

After endlessly surfing to the web, i finally found this unique and rare picture of our navy sous-marin.

much better than forcing them to be installed in Frigate

Adding to this, our Nagapasa-class uses Non-hull penetrating mast for their periscope and sensor. So there are no 'pipe' that penetrate the pressure hull to the conning tower on these boats.

It's half right, but i have to correct this, we still use the conventional periscope, along with the non-penetrating periscope (they called it Optronic Mast ((optical electronic))). The vendor choosen for this is the old player in periscope business, Hensoldt AG.

The Sero 400 series and OMS 100 series is used in this submarine

in this picture, Pak Dhe is using the Sero 400 series, this is the conventional periscope

The other one, OMS 100 series is non-penetrating periscope, as you see in this chart

The Optronic Mast it has unique features

The existence of this periscope, SERO and OMS is confirmed here

From the blueprint the periscope is penetrating the pressure hull.

I stand corrected, forgot they also get the SERO other than the OMSes,

Good sign indeed as our KASAL knows about submarine, lets hope for the best that future assets of AL whether its above or under water can fit the needs of user.

He needs to consider that post 2030 this will be the most dangerous threat to our shipping.

I hope submarine procurement goes in line with the advancement of potential foe, both North and South.

Submarine facility from what i read from media

PT PAL Indonesia is collaborating with the SCS Group to increase the use of domestic components, so as to reduce dependence on imports.
