VTOL UAV.

This is coolbert:

The Thai navy has Marcus-B. The Russian has O4e0596 VTOL drone. The former strictly as this stage of development confined to naval over-the-horizon reconnaissance. The latter now "weaponized" able to carry a 76 mm naval artillery round.

It seems relatively easy to "weaponize" these drones. Strap-on munitions make even small -sized drone lethal! Both Thai and Russia drones in this case battery powered only? Making for a comparatively quiet approach. Almost silent.

There is merit to this mode of operation!
