As the age of manned submarines and aircraft carriers fades, the U.S. Navy must shift its focus toward Unmanned Underwater Vehicles (UUVs) like DARPA’s prototype, the Manta. UUVs offer a more affordable and scalable alternative to traditional nuclear submarines, which the U.S. struggles to maintain in adequate numbers. ?As the age of manned submarines and aircraft carriers fades, the U.S. Navy must shift its focus toward Unmanned Underwater Vehicles (UUVs) like DARPA’s prototype, the Manta.

Keep learning. .. Why are submarines so slow? Submarines are among the most fascinating and powerful machines in the world. They can dive deep into the oceans and perform various tasks, such as spying, attacking, exploring, or rescuing. However, they are also known for being very slow compared to other vehicles. The average speed of a submarine is around 5 to 10 knots, which is equivalent to 6 to 12 miles per hour. This is much slower than the speed of a car, which can travel at around 60 miles per hour. Why are submarines so slow? There are several reasons for this. One reason is that submarines are designed to be stealthy and avoid detection, which requires them to move slowly to minimize the noise they make. Submarines use propellers or jet propulsion to move through the water, but these also create sound waves that can be picked up by sonar or hydrophones. The faster the submarine moves, the louder it becomes, and the easier it is for enemies to locate and track it. Therefore, submarines have to balance their speed and their stealth, and often choose to sacrifice the former for the latter. Another reason is that submarines are bulky and heavy, and not designed for speed, but rather for endurance and carrying large payloads. Submarines have to carry a lot of equipment and weapons, such as torpedoes, missiles, mines, sensors, batteries, fuel, and crew. They also have to withstand the high pressure and low temperature of the deep sea. All these factors add weight and drag to the submarine, making it harder to accelerate and maneuver. Submarines are also limited by their power source, which can be diesel-electric or nuclear. Diesel-electric submarines have to surface periodically to recharge their batteries using air-breathing engines, which reduces their speed and stealth Nuclear submarines can stay submerged for longer periods of time, but they also generate more heat and noise. Despite their slow speed, submarines are still an important part of modern warfare. #warfare #machine #submarine #sea #seashores

The Lockheed CL-1201 was a design study by Lockheed for a large 6,000 ton nuclear-powered transport aircraft in the late 1960s. One envisioned use of the concept was as an airborne aircraft carrier.[1] CL-1201 A mockup of the CL-1201 Artist's impression of the aircraft Role Transport Designer Lockheed Status Design study Primary user United States Air Force (projected) Number built None Developed from CL-1170[1] Although the Department of Defense does not appear to have records of the study's ultimate outcome, the design itself has nonetheless been cited in several sources. The CL-1201 design project studied a nuclear-powered aircraft of extreme size, with a wingspan of 1,120 feet (340 m).[4] Had it been built, it would have had the largest wingspan of any airplane to date,[5] and certainly more than twice that of any aircraft of the 20th century. The wing would be of crescent form, similar to the British Handley Page Victor V-bomber, but unlike the British design, it was tailless.

A lot of great points made in this article regarding the transformational capabilities brought by the integration of UUVs onto submarines.?While torpedo tube launch and recovery does potentially come at the cost of reducing the weapons loadout, there are many ways to get UUVs into the battlespace.?The latest generation REMUS 620 medium class UUVs have endurance in excess of 100 hours and 275nm range making it practical to swim in over long distance and rendezvous with submarines, bringing all the advantages of offboard sensors and effectors that are interoperable, but not necessarily delivered by a host submarine.? We are just now starting to scratch the surface of what is possible with manned/unmanned teaming in the undersea domain.?It is a tremendous step forward that these capabilities are going into operational use.?The lessons learned will be invaluable.??

Microcomputer compensated crystal oscillators or MCXOs, are the ideal choice in many applications, including military and commercial avionics, ground-based electronics, as well as undersea oil exploration. These smaller, lighter, lower-power devices can often replace bulkier and power-consuming oven-controlled crystal oscillators (OCXOs), while also providing comparable stability over a wide range of operating temperatures. This article describes the topology of MCXOs and describes the technological advances that are enabling MCXO deployment in a wide range of space applications. - Q-Tech Corporation Check out - https://ow.ly/AmRg50TrMml #oscillator #crystal #space #satellite #military #avionics #article #industry

TECHNOLOGY BEHIND, LAUNCH OF INTERCONTINENTAL MISSILES. The launch of intercontinental ballistic missiles (ICBMs) involves sophisticated technology, precision, and strategic planning, making it a fascinating subject. Here are some unique and extraordinary facts about how they are launched: ICBMs are typically launched from secure underground silos, submarines, or mobile platforms to ensure survivability and flexibility in deployment. The launch process starts with a complex sequence of commands that only a select few can authorize, often requiring dual control to prevent unauthorized launches. Solid rocket fuel is commonly used for ICBMs due to its stability and ability to be stored for long periods without degrading, ensuring readiness at all times. Upon launch, an ICBM travels through three stages: the boost phase, where it accelerates to leave the atmosphere; the midcourse phase, where it coasts in space; and the re-entry phase, when it descends towards its target. In the boost phase, powerful rocket engines propel the missile out of the atmosphere at incredible speeds, often reaching up to 15,000 miles per hour. ICBMs rely on advanced guidance systems, often combining gyroscopes, accelerometers, and GPS to navigate across vast distances with remarkable accuracy. Some ICBMs use MIRVs (Multiple Independently Targetable Reentry Vehicles), allowing a single missile to carry several warheads, each targeting a different location. During the midcourse phase in space, the missile's warheads are protected by a special shroud, which is jettisoned once they’re on course, making them harder to detect and intercept. Re-entry vehicles are equipped with heat shields made from advanced materials to withstand the intense heat generated as they re-enter Earth’s atmosphere, which can reach over 3,000 degrees Fahrenheit. Missiles are designed to evade interception by maneuvering or releasing decoys to confuse enemy defense systems, enhancing their chances of reaching the intended target. ICBM launches are monitored using advanced satellite systems and radar, which can detect and track launches almost immediately, enabling response strategies. The launch protocols and safety systems for ICBMs are incredibly strict, with continuous training, safeguards, and backup systems to prevent accidental launches and ensure precise control.
