πŸ”— Soviet Lun-Class Ekranoplan Ground Effect Vehicle

πŸ”— Aviation πŸ”— Military history πŸ”— Military history/Military aviation πŸ”— Aviation/aircraft project πŸ”— Military history/Maritime warfare πŸ”— Military history/Russian, Soviet and CIS military history πŸ”— Aviation/Soviet aviation

The Lun-class ekranoplan is a ground effect vehicle (GEV) designed by Rostislav Evgenievich Alexeyev in 1975 and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s.

It flew using the lift generated by the ground effect of its large wings when within about four metres (13Β ft) above the surface of the water. Although they might look similar to regular aircraft, and have related technical characteristics, ekranoplans like the Lun are not aircraft, seaplanes, hovercraft, nor hydrofoils. Rather, "ground effect" is a distinct technology. The International Maritime Organization classifies these vehicles as maritime ships.

The name Lun comes from the Russian word for harrier.

πŸ”— Iran Air Flight 655 (Wikipedia)

Iran Air Flight 655 was a scheduled passenger flight from Tehran to Dubai via Bandar Abbas that was shot down on 3Β July 1988 by an SM-2MR surface-to-air missile fired from USSΒ Vincennes, a guided-missile cruiser of the United States Navy. The aircraft, an Airbus A300, was destroyed and all 290 people on board were killed. The jet was hit while flying over Iran's territorial waters in the Persian Gulf, along the flight's usual route, shortly after departing Bandar Abbas International Airport, the flight's stopover location. The incident occurred during the final stages of the Iran–Iraq War, which had been continuing for nearly eight years. Vincennes had entered Iranian territory after one of its helicopters drew warning fire from Iranian speedboats operating within Iranian territorial limits.

The reason for the shootdown has been disputed between the governments of the two countries. According to the U.S., the Vincennes crew had incorrectly identified the Airbus as an attacking F-14 Tomcat, a U.S.-made jet fighter that had been part of the Iranian Air Force inventory since the 1970s. While the F-14s had been supplied to Iran in an air-to-air configuration, the Vincennes crew had been briefed that the Iranian F-14s were equipped with air-to-ground ordnance. Vincennes had made ten attempts to contact the aircraft both on military and on civilian frequencies, but had received no response. According to Iran, the cruiser negligently shot down the aircraft, which was transmitting IFF squawks in Mode III, a signal that identified it as a civilian aircraft, and not Mode II as used by Iranian military aircraft. The event generated a great deal of criticism of the United States. Some analysts blamed the captain of Vincennes, William C. Rogers III, for overly aggressive behavior in a tense and dangerous environment. In the days immediately following the incident, President Ronald Reagan issued a written diplomatic note to the Iranian government, expressing deep regret. However, the U.S. continued to insist that Vincennes was acting in self-defense in international waters.

In 1996, the governments of the U.S. and Iran reached a settlement at the International Court of Justice which included the statement "...Β the United States recognized the aerial incident of 3Β July 1988 as a terrible human tragedy and expressed deep regret over the loss of lives caused by the incidentΒ ..." When President Ronald Reagan was directly asked if he considered the statement an apology, Reagan replied, "Yes." As part of the settlement, even though the U.S. government did not admit legal liability or formally apologize to Iran, it still agreed to pay US$61.8 million on an ex gratia basis in compensation to the families of the Iranian victims. The shootdown was the deadliest aviation disaster involving an Airbus A300.

πŸ”— K-219

πŸ”— Military history πŸ”— Military history/Maritime warfare πŸ”— Ships πŸ”— Military history/Russian, Soviet and CIS military history

K-219 was a Project 667A Navaga-class ballistic missile submarine (NATO reporting name Yankee I) of the Soviet Navy. It carried 16 R-27U liquid-fuel missiles powered by UDMH with nitrogen tetroxide (NTO), and equipped with either 32 or 48 nuclear warheads.K-219 was involved in what has become one of the most controversial submarine incidents during the Cold War on Friday 3 October 1986. The 15-year-old vessel, which was on an otherwise routine Cold War nuclear deterrence patrol in the North Atlantic 1,090 kilometres (680Β mi) northeast of Bermuda, suffered an explosion and fire in a missile tube. While underway submerged the seal in a missile hatch cover failed, allowing high-pressure seawater to enter the missile tube and owing to the pressure differential rupture the missile fuel tanks, allowing missile's liquid fuel to mix and ultimately combust. Though there was no official announcement, the Soviet Union claimed the leak was caused by a collision with the submarine USSΒ Augusta. Although Augusta was operating within the area, both the United States Navy and the commander of K-219, Captain Second Rank Igor Britanov, deny that a collision took place.

The incident was novelized in the book Hostile Waters, which reconstructed the incident from descriptions by the survivors, ships' logs, the official investigations, and participants both ashore and afloat from the Soviet and the American sides.

πŸ”— Communication with Submarines

πŸ”— Technology πŸ”— Military history πŸ”— Military history/Military science, technology, and theory πŸ”— Military history/Maritime warfare

Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies. Submarines can surface and raise an antenna above the sea level, then use ordinary radio transmissions, however this makes them vulnerable to detection by anti-submarine warfare forces. Early submarines during World War II mostly traveled on the surface because of their limited underwater speed and endurance; they dove mainly to evade immediate threats. During the Cold War, however, nuclear-powered submarines were developed that could stay submerged for months. Transmitting messages to these submarines is an active area of research. Very low frequency (VLF) radio waves can penetrate seawater a few hundred feet, and many navies use powerful VLF transmitters for submarine communications. A few nations have built transmitters which use extremely low frequency (ELF) radio waves, which can penetrate seawater to reach submarines at operating depths, but these require huge antennas. Other techniques that have been used include sonar and blue lasers.

Project Habakkuk or Habbakuk (spelling varies) was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete (a mixture of wood pulp and ice) for use against German U-boats in the mid-Atlantic, which were beyond the flight range of land-based planes at that time. The idea came from Geoffrey Pyke, who worked for Combined Operations Headquarters. After promising scale tests and the creation of a prototype on a lake (Patricia Lake, Jasper National Park) in Alberta, Canada, the project was shelved due to rising costs, added requirements, and the availability of longer-range aircraft and escort carriers which closed the Mid-Atlantic gap the project was intended to address.

πŸ”— Midget submarine

πŸ”— Military history πŸ”— Military history/Maritime warfare πŸ”— Ships

A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to 6 or 9, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff.

Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships.

Most early submarines would now be considered midget submarines, such as the United States Navy's USSΒ HollandΒ (SS-1) and the British Royal Navy's HMSΒ Holland 1.

The Venetian Arsenal (Italian: Arsenale di Venezia) is a complex of former shipyards and armories clustered together in the city of Venice in northern Italy. Owned by the state, the Arsenal was responsible for the bulk of the Venetian republic's naval power from the late Middle Ages to the early modern period. It was "one of the earliest large-scale industrial enterprises in history".

The British Royal Navy established the West Africa Squadron at substantial expense in 1808 after Parliament passed the Slave Trade Act of 1807, an Act for the Abolition of the Slave Trade. The squadron's task was to suppress the Atlantic slave trade by patrolling the coast of West Africa. With a home base at Portsmouth, England, it began with two small ships, the 32-gun fifth-rate frigate HMSΒ Solebay and the Cruizer-class brig-sloop HMSΒ Derwent. At the height of its operations, the squadron employed a sixth of the Royal Navy fleet and marines. In 1819 the Royal Navy established a West Coast of Africa Station and the West Africa Squadron became known as the Preventative Squadron. It remained an independent command until 1856 and then again 1866 to 1867. Between 1830 and 1865, more than 1,500 British sailors died on their mission of freeing slaves with the West Africa Squadron.

Between 1808 and 1860 the West Africa Squadron captured 1,600 slave ships and freed 150,000 Africans. It is considered the most costly international moral action in modern history.

The Squadron has been described as being poorly resourced and plagued by corruption; it only managed to capture around 6% of the transatlantic slave ships, but patrolling 3,000 miles of African coast from 1808 to 1860 it liberated 150,000 Africans.

The USS Liberty incident was an attack on a United States Navy technical research ship (spy ship), USSΒ Liberty, by Israeli Air Force jet fighter aircraft and Israeli Navy motor torpedo boats, on 8 June 1967, during the Six-Day War. The combined air and sea attack killed 34 crew members (naval officers, seamen, two marines, and one civilian NSA employee), wounded 171 crew members, and severely damaged the ship. At the time, the ship was in international waters north of the Sinai Peninsula, about 25.5 nautical miles (47.2Β km; 29.3Β mi) northwest from the Egyptian city of Arish.

Israel apologized for the attack, saying that the USS Liberty had been attacked in error after being mistaken for an Egyptian ship. Both the Israeli and U.S. governments conducted inquiries and issued reports that concluded the attack was a mistake due to Israeli confusion about the ship's identity. Others, including survivors of the attack, have rejected these conclusions and maintain that the attack was deliberate.

In May 1968, the Israeli government paid US$3.32Β million (equivalent to US$29.1Β million in 2023) to the U.S. government in compensation for the families of the 34 men killed in the attack. In March 1969, Israel paid a further $3.57Β million ($29.6Β million in 2023) to the men who had been wounded. In December 1980, it agreed to pay $6Β million ($22.2Β million in 2023) as the final settlement for material damage to the ship plus 13 years of interest.

πŸ”— Turtle (Submersible)

Turtle (also called American Turtle) was the world's first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against Royal Navy vessels occupying North American harbors during the American Revolutionary War. Connecticut Governor Jonathan Trumbull recommended the invention to George Washington, who provided funds and support for the development and testing of the machine.

Several attempts were made using Turtle to affix explosives to the undersides of British warships in New York Harbor in 1776. All failed, and her transport ship was sunk later that year by the British with the submarine aboard. Bushnell claimed eventually to have recovered the machine, but its final fate is unknown. Modern replicas of Turtle have been constructed and are on display in the Connecticut River Museum, the U.S. Navy's Submarine Force Library and Museum, the Royal Navy Submarine Museum, and the Oceanographic Museum (Monaco).
