中方正在擴大海軍，但可能仍有重要的計畫尙未曝光。有兩艘不明潛航器已秘密部署南海三亞海軍基地，而這初步的跡象或許顯示，解放軍還有更大的計畫。 6park.com
據《海軍新聞》（Naval News）網16日報導，英美海軍都在研製超大無人潛航器（XLUUV）。廣泛認為，它們將成為未來艦隊的關鍵要角。而誰先發展，誰就可能享有顯著優勢。 6park.com
而中方海軍也有類似計畫，其實並不令人意外，但在這之前，始終沒有相關細節出現。海南三亞海軍基地的衛星影像顯示，當地出現了兩艘超大無人潛航器。它們雖然從2021年3—4月就在當地，但直到目前才曝光。而跡象顯示，它們在試驗或測試。 6park.com
三亞不僅是南海重要的海軍基地之一，也是作戰潛艦的母港。而新型超大無人潛航器曝光的碼頭，就靠近中國先前的微型潛艦基地。 6park.com
而美國衛星公司馬薩爾科技（Maxar Technologies）衛星所拍攝的高解析度影像，就放在谷歌地球（Google Earth）上。 6park.com
初步評估顯示，這兩個黑色物體是超大無人潛航器，因為它們太小，不會是一般潛艦，但又太大，不可能是潛水推送器（SDV）。這兩艘潛航器大小不一，設計似乎也截然不同。而這顯示，不同的原型或驗證潛航器在互較高下，進行測試。 6park.com

第一艘無人潛航器約長16米、寬2米，有流線型艦艏，而尾部似乎有兩個並排的螺旋槳。 6park.com
有趣的地方在於，這或許顯示，它和HSU-001大型水下無人載具（LDUUV）有關。HSU-001最初是在2019年9月亮相，據信已服役，但至今披露的細節並不多。不過，新潛航器比HSU-001大了不止一倍。 6park.com
事實上，新潛航器的大小酷似美國海軍的「殺人鯨」（Orca）超大無人潛航器。可是波音（Boeing）打造的第一艘「殺人鯨」4月才命名，但中方海軍的無人潛航器原型似乎在2021年，甚至更早就已下水。 6park.com
從外觀來看，另一艘超大無人潛航器設計則比較簡單，它雖然細窄得多，但比較長，約達18米。而它的設計令人聯想起和「殺人鯨」打對臺，由洛克希德馬丁（Lockheed Martin）的超大無人潛航器。 6park.com
廣泛認為，超大無人潛航器可能帶來海戰革命，如今中型無人潛航器能執行情監偵（ISR）任務，而超大版則意味著它們的航程要長得多，也開啟了執行其他任務的可能，如佈雷，打反潛戰和運輸等。 6park.com

China’s New Extra-Large Submarine Drones Revealed              
              
             

               China's naval expansion may have a key program which was 
not previously reported. Secretly deployed to the South China Sea, two 
unknown underwater vehicles have been seen at Sanya naval base. This may
 be the first indication of a much larger program.

The U.S. Navy and Royal Navy are both pursuing extra-large uncrewed underwater vehicles
 (XLUUVs). These drone submarines are widely seen as a key part of 
tomorrow’s fleet. And the early movers may have a significant advantage. 6park.com
It is no surprise that the Chinese Navy (PLAN) also appears to have a
 corresponding program. Yet no details have been available until now. 6park.com
Satellite imagery of Sanya naval base on Hainan in the South China 
Sea reveals two XLUUVs. The two vehicles have been present since 
March-April 2021, but have only come to light now. The arrangement 
indicates trials or testing. Sanya is part of a series of important 
naval bases in the area and is home to operational submarines. The quay 
where the new XLUUVs have been seen is near to where China previously 
based midget submarines. 6park.com
The high-resolution imagery, taken by Maxar Technologies’ satellites,
 is available in Google Earth. Google Earth is one of the oldest Open 
Source Intelligence (OSINT) tools in the defense space. With the advent 
of near-daily satellite passes from other sources it can be overlooked, 
but checking its latest updates can yield rewards. 6park.com
Extra-Large Uncrewed Underwater Vehicle
 6park.com
Our preliminary assessment points to the two black objects being 
XLUUVs (Extra-Large Uncrewed Underwater Vehicle). These are too small to
 be regular submarines, and too large to be swimmer delivery vehicles 
(SDVs). 6park.com
The two submersibles are different sizes and appear to be 
significantly different designs. This suggest a competitive trial of 
different prototypes or demonstrators. 6park.com
The first XLUUV is around 16 meters (52 feet) long and 2 meters (6.4 
feet) across. It has a streamlined bow. At its tail, it appears to have 
two propellers (screws) in a side-by-side arrangement. This is 
interesting because it may indicate a link to the HSU-001 LDUUV. 6park.com
(Large Displacement Unmanned Underwater Vehicle). The HSU-001 was first shown in public
 in September 2019 and is believed to be in service with the PLAN, 
although few details have emerged since. The new vehicle is more than 
twice the size however. 6park.com
 6park.com
The Orca XLUUV Test Asset System prepares for the first 
in-water test following a christening ceremony April 28, 2022, in 
Huntington Beach, California. The Orca XLUUV program is tailored to 
address joint warfighting needs with a sense of urgency. Boeing photo. 6park.com
The new submersible’s size is very similar to the U.S. Navy’s Orca 
XLUUV. Developed by Boeing, that system is seen as the first-mover in 
this space. However the first Orca was only christened in April, while 
it appears that the PLAN have had their prototypes in the water since 
2021 or earlier. 6park.com
The other XLUUV is outwardly simpler in form. It is much slimmer but 
also longer, around 18 meters (59 feet). This design is reminiscent of Lockheed Martin’s contender for the U.S. Navy’s Orca XLUUV program. 6park.com
Implications
 6park.com
XLUUVs are widely seen as key naval technologies which might shape 
future conflicts. Like existing mid-sized UUVs they can perform ISR 
(intelligence, surveillance and reconnaissance) missions. Their greater 
size however should translate into much longer ranges. It also opens up 
other roles, such as offensive minelaying, anti-submarine warfare and 
transport. 6park.com
As is the nature of intelligence, the new vehicles may turn out to be
 something other than XLUUVs. However whatever they are, they are likely
 interesting and relevant for defense analysts. 6park.com
China has been building up and modernizing its Navy for the past 20 
years. This has included a number of advanced underwater vehicles, some 
of which have not been publicly acknowledged. So while this latest 
program may come as a surprise, it shouldn’t. It is a reminder of 
China’s growing naval power and ambitions. And that it can build up new 
capabilities in relative secrecy.
