Bangladesh, Philippine, Burma and Thailand Submarine Issues

India feels threatened by the prospect of increasing Chinese submarine proliferation in the Indian Ocean. Such proliferation comes through such means as:

-  Chinese anti-piracy conventional and nuclear propelled subs moving across the Indian Ocean for operations off the Horn of Africa,
-  submarine visits to such ports as Columbo, Sri Lanka, and
-  sale of Chinese subs to such Indian neighbours as Bangladesh (around 2019) and perhaps in future to Burma and Pakistan (see India's "West Coast Worries").

For more than a year there have been reports of a pending sale of obsolescent Chinese Ming-class submarines to Bangladesh. See my article http://gentleseas.blogspot.com.au/2013/12/china-selling-two-type-035-ming-class.html of December 24, 2013. It is highly likely that, after expected delivery of the Mings in 2019, part of a Bangladesh Ming crew and on-shore maintainers would be Chinese for a transition period. This would cause a range of anxieties in India.

In late 2014 Indian intelligence and the Indian Ministry of External Affairs have pushed the possibility (or for India a hope) that Bangladesh might buy Russian submarines instead.

It is unclear whether these "Russian" Submarines would be:
- new build Kilos (surely too expensive for Bangladesh without credit-finance)
- used Kilos from Russia (cheaper but probably unreliable with a short remaining service life) or
- ex-Indian Kilos (cheaper but probably unreliable with a short remaining service life).

Two nations that probably will not buy submarines in the short to medium term are:

- the Philippines (it usually receives low-or-no cost used naval and coastguard vessels) - see http://thediplomat.com/2014/12/the-philippine-navys-submarine-quest/  December 31, 2013

- Thailandhttp://thediplomat.com/2015/01/thailand-eyes-submarine-fleet/, January 4, 2015,
  Pete's Comment: If Thailand bought used Ming subs from China Thailand might receive them in 2019 - depending on Chinese modifications. Used Kilos are harder to estimate. If Thailand prefered 2 or 3 new submarines costs would be much higher and involve:
- significant lead times for negotiating, ordering and building submarines - generally around 6 years for a new customer like Thailand
- in the case of South Korea as a supplier a backlog of pre-existing orders might perhaps cause delays. This may mean a minimum delivery year of 2020 for Thailand to receive the first sub then add 3 years for commissioning (tests, trials and training) the sub into the Thai Navy ie. 2023.

China selling two Type 035 Ming-class submarines to Bangladesh

------------------

http://thediplomat.com/2013/12/china-to-sell-bangladesh-2-submarines/ based on a Bangladeshi New Age article http://newagebd.com/detail.php?date=2013-12-20&nid=77363#.Urjor2fxvX5

The Ming-class submarines (Type 035) are medium sized diesel-electric submarines. In the 1960s China reverse engineered the Russian Romeo Class into the Chinese Romeo-class Type 033. The Ming-class Type 035 were developed in the 1970s from the Romeo Type 033. China built more than 20 Mings from the 1980s to 2000s in part as a hedge against more risky, higher tech conventional sub projects being delayed particularly the Song-class, Type 039 submarine


Globalsecurity reports that compared to the Romeos the Ming features more powerful diesel-electric propulsion, higher battery capacity, improved propeller and maneuverability, improved seakeeping and underwater endurance and is quieter. 

Chinese Defence Today reports that the Ming has a improved, more streamlined hull design than the Romeos, new engine gearing, all resulting in increased submerged speed. transferring mechanism were used to achieve a higher underwater speed. The Ming also has an improved combat system.





On February 28, 2014 Ahmed Sharif provided some valuable clarifying comments:
"Bangladesh's submarine program is at least 10 years old. In March 2004, a govt. minister told the Parliament about buying 4 subs by 2012. But due to political turmoil, the program got delayed, until late 2008, when a naval confrontation with Myanmar accelerated everything. The program got more acceleration after reports of Myanmar Navy's plans to acquire subs. Over the years, at least 100 sailors received submarine training both in Turkey and in China. There's no reason to believe that the subs would be operated by 17 sailors. Of course initial operation may require Chinese help, but Bangladesh Navy sets a high standard in training and operations, which indicates that even if there is Chinese assistance, it would be for a very short period of time. And these subs are arriving in 2015, not in 2019. This was recently confirmed by a high-placed govt. official to the media. And on another note, the 2 subs are likely to be first batch of a bigger submarine arm. Things are likely to be determined by the economic growth of the country."

SPECIFICATIONS  for China's Type 035 Ming-class submarinefrom in Chinese Defence Today dated May 10, 2006, include: 

TORPEDOES

Eight 533mm torpedo tubes (6 bow, 2 stern), carrying a total of 18 torpedoes in tubes and storage racks. Alternatively the submarine can carry 32 mines in its tubes.

The Yu-4 (SAET-60) is a passive homing torpedo designed to attack surface targets up to 15km at a speed of 40 knots. The high-explosive warhead weights 400kg.

The Yu-1 is reverse engineered from the Russian Type 53-51, which was designed to attack surface targets with a maximum range of 9.2km at a speed of 39 knots, or 3.7km at 51 knots. The high-explosive warhead weights 400kg.

SENSORS

Fitted with a Pike Jaw hull-mounted, medium-frequency for active and passive search and attack. Later Mings are also equipped with a Sintra DUUX 5 low-frequency passive ranging and interception. The Ming has an I-band surface search radar (NATO code-name: Snoop Tray).

Countermeasures include electronic support measures (ESM), radar warning receiver and direction-finder.

PROPULSION

Diesel-electric arrangement, consisting of 2 Shaanxi 6E 390 ZC1 diesel rated at 5,200hp (3.82MW), with 2 Xiangtan alternators and 2 shafts.

Displacement (Surface): 1,584 tons
Displacement (Submerged): 2,113 tons
Length: 76m
Beam: 7.6m
Draft: 5.1m
Speed: (Surfaced) 15 knots, (Dived) 18 knots, (S
norting) 10 knots 
Diviing Depth: N/A
Endurance: 8000 miles at 8 knots snorting, 330 at 4 knots dived.
Crew: 57 (10 officers)

PETE's COMMENT

It must be remembered that the Ming is a improvement on basic 1950s Russian submarines. Its (pre-teardrop) design and electronics may make the current Ming equivalent to a British Oberon Class submarine of the early 1970s. That said the Ming is inexpensive so Bangladesh can probably afford two.

Bangladesh's two Mings, when handed over by 2019 are probably strongest in brown and green water defensive warfare in the northern Bay of Bengal around Chittagong.
