There were other navies that carried infantry on ships before the Dutch, but I think the Dutch were the first to have them do amphibious operations, most notably in the 2nd Anglo-Dutch war where they captured forts en-route to chatham.

The CIWS gun is definitely home made as well! Only the cannon itself is bought from the US: the 30-mm Avenger Gatling cannon. All radar, tracking and targeting systems around it are Dutch. It is called "Goalkeeper", and is sold to several navies around the world by Thales Hengelo.

It has nothing to do with sound, and the spikes are metal. It is a room for testing large radars, and the spikes absorb radio energy, both to improve measurement quality and to protect bystanders. The radars can cook a person to death in seconds, like a micro-wave on steroids...

4:00 That is a SMART-L radar being tested in a special room. The metal spikes absorb radio energy, so the measurement equipment only measures what comes from the antennae--not what is bounced back by the walls. It also ensure no energy escapes the room, which would be dangerous for the engineers. These radars can cook a guy to death in seconds, like a microwave on steroids. The Netherlands develops its own world-class radar and C&C systems. 5:00 That was an old mine being detected and destroyed. Probably a left over from WW2 (or even WW1). The divers probably attached a satchel charge to detonate it, though there are other ways to dispose of them. 7:00 The Dutch Navy has a detachment doing coast-guard duties in the Dutch Caribbean, that is where a lot of drug runs are intercepted. The Dutch Caribbean does not have its own coast guard. The European Netherlands do have a coast guard and water police. The anti-piracy clips were from detachments operating in the Gulf of Aden, alongside e.g. the US navy. 8:00 That was in Sint Maarten, one of the Dutch Caribbean islands that was hit hard by a hurricane a few years ago.
