Navies developing radical future submarine concepts and technologies from mind controlled, ultrafast, laser communications to launching UUVs and UAVs.

Germans were first to demonstrate the revolutionary capability of submarines in World War I, by both sinking enemy combatants and interdicting commerce. Modern Submarines have become one of the deadliest weapons which are hardest to detect, literally a pile of submerged nuclear weapons ready to unleash widespread destruction with single command. In case of a nuclear war the stealthy submarines have a greater chance of surviving the first strike. Once on high alert the boats can leave their bases stay undetected for months and can carry and fire missiles that could sink even the sturdiest ship and flatten entire cities. Also worthy of note in this context is the coupling of two formerly disruptive technologies – nuclear propulsion and missiles – to provide the Submarine Force with two of our most unique capabilities today: submarine-launched ballistic missiles and no-notice land attack using Tomahawk.

However, submarines still face many challenges: Building a hull strong enough to withstand the water pressure while keeping atmospheric pressure inside. Not just the hull itself, but any windows, hatches, electrical fittings, levers etc. Military submarines which can travel a large distance cannot dive very deep, while the deep-diving submersibles are small and cannot go very fast or carry supplies (air, food, water, fuel) to go very far. It’s easier and cheaper to send robot vessels.

Researchers are developing new concepts and technologies for submarines from sonar absorbent composites, advanced propulsion systems like AIP and nuclear, mind controlled, ultrafast, laser based communications to launching UUVs and UAVs.

US navy’s recent Virginia-class attack submarines provide the Navy with the capabilities required to maintain the nation’s undersea supremacy well into the 21st century. It has Virginia Payload Modules whose real strength lies in the ability of these tubes to hold other payloads. Alternative payload modules, both in development today and in the future, can replace the standard Tomahawk compartment. Sensor payloads under development include a submerged launched Unmanned Aerial Vehicle (UAV) and a remotely launched Unmanned Underwater Vehicle (UUV).

Royal Navy project shows how underwater warfare could look in 50 years’ time

The UK’s brightest and most talented young engineers and scientists came up with the designs after being challenged by the Royal Navy to imagine what a future submarine would look like and how it would be used to keep Britain safe in decades to come.

The concepts unveiled include a crewed mother ship shaped like a manta ray. This mothership would be capable of launching unmanned underwater vehicles shaped like eels, which carry pods packed with sensors for different missions. These pods can damage an enemy vessel, or dissolve on demand at the end of an operation to evade detection. The mother ship shall launch fish-shaped torpedoes to swarm against enemy targets would be crewed by only 20 people, who would use their minds to control the ship.

The whale shark/manta ray-shaped mothership would be built from super-strong alloys and acrylics, with surfaces which can morph in shape. With hybrid algae-electric cruising power and propulsion technologies including tunnel drives which work similarly to a Dyson bladeless fan, the submarine could travel at unprecedented speeds of up to 150 knots.

Unlike the submarines of today, which perform multiple roles in one hull, it is envisaged that the Royal Navy of the future would operate a family of submarines of various shapes and sizes, both manned and unmanned, to fulfill a variety of tasks.

Commander Peter Pipkin, the Royal Navy’s Fleet Robotics Officer, said: “With more than 70 per cent of the planet’s surface covered by water, the oceans remain one of the world’s great mysteries and untapped resources. “It’s predicted that in 50 years’ time there will be more competition between nations to live and work at sea or under it. So it’s with this in mind that the Royal Navy is looking at its future role, and how it will be best equipped to protect Brit

 

Russian submarines to receive new sonar absorbent composites

Russia’s Krylov State Research Center (KSRC) has developed innovative new technologies, which will reduce the ability of sonar to detect Russian submarines, according to Valeriy Shaposhnikov, chief of KSRC’s endurance and shipping hull construction unit.

 

“We have developed the appropriate technologies and constructions made of composites,” Shaposhnikov said. These new multilayer composites the company is using have a structure and consistency that absorb sonar signals, thereby preventing the detection of a submarine via hydroacoustics. “Such effect is provided by the extremely complex inner structure of the composite developed by KSRC,” he added. According to Shaposhnikov, the control surfaces of a submarine like rudder blades can be made from the new composites.

 

Laser based Submarine communications

Submarine communications have always been a challenge because radio waves can’t penetrate sea water. Ultra-low frequency electromagnetic waves have been used but are a slow method of communicating. Submarines are completely reliant on satellites for communications and orders from their commanders ashore. A command and control denied environment (C2DE) is an area in which communications are jammed or degraded. There is no technology currently available that allows submarines to conduct communications in a C2DE. The only method currently available is for the submarine to navigate to unaffected waters, conduct all of its communications, and then to travel back to the C2DE, wasting valuable time and possibly compromising the submarine’s mission. However, Satellite communications require submarines to briefly surface and the use of towed antennae compromise the ability of the vessel to remain stealthy.

 

Blue-green lasers is a potential technique for high bandwidth underwater wireless communication because of its high data transfer rate, reasonably large range, small size, low power consumption, immunity to interference and jamming and covertness of transmission. The laser works in much the same way as a fiber optic cable, with the medium for data transfer being the air instead of the cable. Blue and blue-green laser wavelengths can penetrate sea water so offer the potential of improved submarine communications.

Combat Power, Access, and Knowledge Superiority

RADM Malcolm Fages, USN stressed the importance of innovation in maintaining the relevance of the Submarine Force in the 21st century. He stressed three factors:  Combat Power, Access, and Knowledge Superiority.

“Combat power emphasizes payload, but even with superior payload capabilities, employing submarines for maximum benefit is critically dependent on access and knowledge superiority. Without the ability to get within range of the target – achieving access – combat power is valueless. And without knowledge superiority, combat power cannot be applied in a timely and coherent fashion for maximum effect.”

Access has two components: Physical access and Electronic access. Submarine is most effective means of enabling assured physical access to a denied area. A well-operated nuclear-powered submarine is invulnerable to coastal cruise missiles, tactical ballistic missiles, and the biological and chemical weapons of mass destruction that are likely to pose growing problems to non-stealthy forces.

The “physical access” our submarines can achieve stem from our acoustic and non-acoustic stealth, and the quality of our sonar and mine reconnaissance equipment – areas of sustained investment by the Submarine Force, but also areas in which we are looking at leading-edge opportunities. And in the future, that access will likely depend increasingly on advanced sensors and payloads. For example, leave-behind sensors, submerged weapon pods that fire when signaled, or submarine launched unmanned aerial vehicles (UAVs) are all plausible means for expanding physical access and for leveraging force structure

Electronic access depends on ACINT and SIGINT capabilities, and is more than just the ability to put submarine sensors into an area where collection is required. The leap forward in onboard submarine processing capabilities – made possible largely by new computer technologies and programs like ARCI – has enabled a paradigm shift in how we collect and process intelligence

We are making similar progress in our SIGINT superiority initiative – combining the enhanced wideband capability of the Type 18I periscope with the “Classic Troll” exploitation suite. Just getting a 3 dB improvement in sensitivity with the Type 18I makes an extraordinary difference in the standoff range available to the submarine in ISR missions.

 

Knowledge Superiority

The Submarine Force can achieve knowledge superiority through network-centric operations, where enormous tactical synergy comes not only from developing, but also sharing, knowledge across the force.

High data rate antenna that will provide data rates in the EHF spectrum up to 256 Kbps, as well as provide access to SHF and GBS communications shall lead to new disruptive capabilities is in covert communications.

High-data rate, covert communications will not only bring extraordinary advantages in warfighting, but will also enable telemedicine, or real-time consultations with technical experts to solve maintenance problems that might otherwise force a ship off station. We might even be on the threshold of having loved ones back home able to send video family-grams to our deployed sailors!

 

Combat Power

Covert, precision strike from a submarine operating in denied areas in the early stages of a conflict will have a profound impact in future engagements. Whether for destroying enemy air defenses, hitting command and control complexes, or neutralizing other key nodes, our ability to strike with surprise from close in will play a disproportionate role in achieving final success. In Afghanistan, our Navy conducted its first attack on targets within a landlocked nation. Significantly, we chose a submarine attack to achieve maximum surprise against Bin Laden’s terrorist camps and thus inflict greater damage. Submarine-launched missiles are particularly potent for other reasons: Tomahawk attrition is reduced, and fired close to shore, they have sufficient range to attack enemy weapon launchers from widely separated azimuths, thus boosting chances of success.

While fixed targets can be hit with GPS, Capability to attack mobile targets, like missile batteries requires real-time intelligence with the reduced flight time of close-in, submarine-launched missiles. Many target sets can be destroyed before they have time to move, and with enemy defenses neutralized at the outset, our strikers can focus on power projection without needing to devote scarce resources to defense suppression. In flight guidance of missiles shall allow striking mobile targets, this requires feedback link from the missile and a floating-wire UHF antenna with both transmit and receive capability

 

“All-electric” submarine

These future capabilities will be greatly facilitated by the “all-electric” submarine. Rather than harnessing most of the nuclear reactor’s output power directly to the propulsion turbines, it will be converted to electric power on a common bus. When there is a high propulsion demand, power can be allocated to the propulsion train. But when propulsion demand is low, as is frequently the case, the Commanding Officer will be able to allocate power from the common bus to a host of functions, including High endurance UUV’s, UAV’s and directed energy weapons systems.
