Can Vietnam's DHC-6 seaplane carry anti-ship missiles?
Thanks to its EL/M-2022A radar and MiniPOP electro-optical system, Vietnam's DHC-6 seaplane can identify surface targets with considerable accuracy.
Currently, the Vietnam Naval Air Force has a squadron of six DHC-6-400 Twin Otter amphibious seaplanes, each valued at $5.6 million, manufactured by Viking Air of Canada.
The DHC-6-400 Twin Otter has a maximum takeoff weight of 5,670 kg and can carry 19 people.
The theoretical ceiling is 7,620 m, while the actual ceiling is 7,431 m. The maximum speed at an altitude of 2,000 m is 307 km/h, and the maximum flight time is 6 hours and 51 minutes.
This amphibious seaplane can be configured for conventional runway takeoffs and landings, or it can be fitted with flotation devices to allow it to take off and land on both water and land, just like the non-flooding version.

However, the most noteworthy equipment on Vietnam's DHC-6 seaplane is the EL/M-2022A maritime surveillance radar system along with the MiniPOP electro-optical-infrared sensor complex.
The EL/M-2022A radar, capable of simultaneously scanning and tracking up to 256 targets at sea with performance rated as "excellent," boasts a maritime surveillance range of up to 200 nautical miles, highlighting its equivalence to the EL/M-2032 fire control radar (equipped on many current fighter aircraft), and allows operation in both air-to-air and air-to-air modes.
In addition, MiniPOP is a high-resolution day/night observation system that provides real-time imagery, automatic target capture, and highly accurate target localization for small attack platforms such as drones, armored vehicles, ground-based unmanned vehicles, and naval warships, playing an active supporting role for the EL/M-2022A radar.

Thus, with the equipment described above, the maritime surveillance capabilities of the DHC-6-400 Twin Otter seaplane are no less than those of the most modern air-to-sea combat aircraft; its only weakness lies in the weapons it carries.
However, according to weapons experts, it is entirely possible to add wing-mounted pylons to the DHC-6-400 in the future to integrate additional anti-ship missiles such as the Kh-35 Uran-E or KCT-15, which are domestically produced in Vietnam.
When equipped with weapons, the DHC-6-400 Twin Otter will be transformed into an extremely formidable air attack aircraft for Vietnam, effectively serving as a support for Su-30MK2 or Su-22M3/M4 fighters in air-to-sea combat.
