Chinese Submarine Drone Discovered Near Gateway To Indian Ocean

H I Sutton  29 Dec 2020

The latest underwater drone found by fishermen may indicate that China is surveying Indonesian waters. This may have strategic implications if it helps Chinese Navy submarines and warships enter the Indian Ocean.

Indonesian fishermen found an underwater drone on December 20th. Based on photographs we can say with some confidence that the drone is closely related to the Chinese Sea Wing family. The find was reported in local media (in Indonesian). It was discovered near Selayar Island in the South Sulawes, far away from China’s adjacent waters.

The find is close to two potential routes between the South China Sea and the Indian Ocean. These routes, the Sunda Strait and Lombok Strait, may be important in wartime. Intelligence gathered by the drone may be valuable to the Chinese Navy if their submarines intend to use these straits.

The object is a type of drone known as a glider. These are unpowered so must use something called variable-buoyancy propulsion. This involves inflating and deflating a balloon-like device filled with pressurized oil. This causes them to sink before rising to the surface again. As they do so they travel along, aided by wings. And as they go, they are gathering data on the ocean environment.


Indonesian based security & defense poster @Jatosint was quick to post the find on Twitter, and make the connection to the Chinese-made Sea Wing glider. Note that the device is upside down in the photos.
The data gathered can included temperature, turbidity, salinity, chlorophyll and oxygen levels. This data may sound innocuous and it is often used for scientific research. But it can also be extremely valuable to naval planners. Especially supporting submarine operations. The better a navy knows the waters, the better it is able to hide its submarines.

The US, France and other countries build and operate similar gliders. However, key characteristics of the Chinese type, which are not found on other similar underwater glides, are present. The nose cone has three circular sensor windows with the central one larger than the outer two. The wings have a folding mechanism and the antenna extends directly out of the center of the tail cone. The vertical stabilizer, like a tail fin, is seen underneath, Ordinarily the devicde would be up the other way with it pointing upwards,

Sea Wing gliders are known to be launched by China’s specialist survey ships. In December 2019 the survey ship Xiangyanghong 06 launched around 12 of the drones into the Eastern Indian Ocean. The one found may be one of these, but it seems unlikely given the ocean currents.

Another Sea Wing glider was found by Indonesian fishermen in March 2019. This was in the Riau Islands, much closer to the South China Sea. The exact variant of Sea Wing was different, but the craft was very similar. However this is enough to suggest that they were deployed at different times and likely in different places. Additionally, camera-like sensors were apparently still operating when it was recovered. This suggests that it was deployed more decently.

Where the glider was originally deployed, and what it was doin, remain unclear. But these craft can provide valuable military intelligence.

China previously protested when it found a similar U.S. Navy glider in international waters near its coast. On December 15, 2016 a Chinese ship plucked a U.S. Navy LBS-G ( Littoral Battlespace Sensing-Glider) out of the South China Sea. The glider was in the process of being recovered by USNS Bowditch. The drone was only returned after the incident escalated.

This incident is unlikely to escalate in the same way, but does serve to draw attention to China’s increasingly assertive maritime activities. These gliders may, in some cases, be innocent, but they are naturally viewed with suspicion. It may be evidence that China is reconnoitering potential submarine routes into the Indian Ocean, through Indonesian waters. Or some other naval plan.

Ribar u moru našao podvodni dron
M.V.A. 01.01.2021.

Na strateškom pomorskom putu od Južnog kineskog mora do Australije pronađen je kineski podvodni dron, tvrde stručnjaci. Kao prenose indonezijski mediji, podvodno vozilo bez posade našao je ribar u blizini ostrva Selajar (provincija Južni Sulavezi) na istoku Indonezije 20. decembra da bi ga šest dana kasnije predao policiji, koja ga je poslala indonezijskoj vojsci.

Vojni posmatrači veruju da je reč o kineskom autonomnom podvodnom vozilu tipa „Sea Wing“, razvijenom u Institutu za automatizaciju kineske Akademije nauka, koji prikuplja i u realnom vremenu prenosi informacije o temperaturi, salinitetu, zamućenosti i nivou kiseonika u morskoj vodi, prenosi „Gardijan“. Kako navodi specijalizovani časopis „Naval News“, prikupljeni podaci mogu biti veoma dragoceni za planiranje mornaričkih operacija, naročito podmorničkih.

– Što mornarica bolje poznaje vode, to uspešnije može da sakrije svoje podmornice - navodi se u časopisu.

Kinu optužuju da želi da proširi teritoriju u spornom Južnom kineskom moru i da obavlja obimna okeanografska istraživanja u regionima za koje veruje da bi mogli biti od vojnog značaja. Godine 2019. Kina je obavila istraživanje okeana na severu Papue Nove Gvineje, gde SAD i Australija imaju zajedničku mornaričku bazu na ostrvu Manus, a u martu ove godine pored Božićnog ostrva, australijske teritorije severozapadno od kontinentalnog dela Australije.

Kako za ABC navodi Muhamed Fauzan, indonezijski analitičar bezbednosti, dron verovatno mapira buduće podmorničke putanje, s obzirom na to da je otkriven daleko od kineskih voda, a na značajnoj pomorskoj ruti između Kine i australijskog najsevernijeg grada Darvina. Fauzan je izjavio da je ovo „najmanje treći put da takav dron, za koji ja i mnogi drugi ljudi, uključujući i stručnjake, verujemo da je podvodni dron kineske proizvodnje, otkriven u indonezijskim teritorijalnim vodama“. On je rekao da se dron još kretao kada su ga ribari našli, da je svetlo treptalo i da su prednji senzori radili.

– Ovo je prvi put da smo čuli da vojska javno govori da su zaplenili dron i da će obaviti sveobuhvatnu analizu u indonezijskoj marini u Surabaji - rekao je Fauzan.

Drugu varijantu podvodnog drona „Sea Wing“ indonezijski ribari otkrili su u martu 2019, u vodama ostrva Rijau bliže Južnom kineskom moru, zatim još jedan u januaru ove godine u Istočnoj Javi, a u decembru 2016. kineski brod ASR-510 približio se na 500 metara američkom ratnom brodu "Boudič" i zaplenio podvodni dron u međunarodnim vodama blizu obale SAD, a vraćen je tek nakon zaoštravanja situacije.
