Submarine

When the first of the Royal Navy's Dreadnought-class nuclear missile submarines takes to the sea in this decade, the same fly-by-wire technology used in aircraft will be used to control all the major facets of the boat's maneuvering.

Resting 12,500 ft below the surface, the wreck of the Titanic has rarely been visited by manned submarines. But Triton's latest luxury sub can take you down there in air-conditioned comfort, and it sports a clever set of articulating gull wings.

Triton has turned its attention back to the luxury sector with a new six-person sub designed to launch from the garage of your mega-yacht. Its giant 2.5-m diameter spherical acrylic pressure hull is the biggest ever, giving panoramic views for six.

If you're on a secret military diving mission, chances are you don't want the enemy to see you getting into the water. That's where VICTA comes in, as it's a diver delivery boat that transforms into a submarine.

More than once, we've seen an "SUV of the high seas," and Officina Armare has a new interpretation. The 60-foot (18.3-m) Aquanaut leaves 4WD on land in favor of dual-hull navigation, bringing along more toys than an SUV ever could ever handle.

Elbit Systems UK's autonomous Seagull Unmanned Surface Vehicle (USV) has completed Anti-Submarine Warfare (ASW) sea trials off the British coast in collaboration with the Ministry of Defence, with the USA's L3Harris providing sonar systems.

3D printing is set to go to sea in the form of an additive manufacturing technique for repairing submarines. Developed by Australia’s ASC, the cold spray printing technology is intended to repair the Royal Australian Navy's Collins Class submarines.

The biggest name in deep-sea exploration has launched an incredible luxury tourist submarine capable of taking 24 passengers 328 feet underwater in air-conditioned comfort, with massive floor-to-ceiling windows providing panoramic views.

Diving into the autonomous submarine race, DARPA has awarded contracts to three companies as part of its Manta Ray Program. The end goal is to produce robotic vehicles that can operate for months without maintenance or human logistics support.

The British government is investing up to £2.5 million (US$3.2 million) to begin the development for the Royal Navy of an extra-large autonomous submarine measuring 100 feet in length – making it larger than the Boeing Orca XLUUV.

While autonomous underwater vehicles (AUVs) do make the gathering of oceanographic data easier, launching the things can still be a hassle. That's why scientists have developed a new system that uses an unmanned surface vessel to deploy an AUV.

Leonardo's ULISSES sonar system recently completed a live sea trial off the coast of Italy. By processing signals from up to 64 sonobuoys and dipping sensors, it was able to accurately locate multiple, simulated submarines.
