Operation Pacific
''Operation Pacific'' is a 1951 black-and-white World War II submarine war drama from Warner Bros. Pictures, produced by Louis Edelman, and written as well as directed by George Waggner. John Wayne and Patricia Neal star and Ward Bond and Philip Carey play supporting roles. Much of the film is set aboard a Gato Class submarine. The technical advisor was World War II Admiral Charles A. Lockwood, Commander, Submarine Forces, Pacific (COMSUBPAC). Plot During World War II, the submarine USS ''Thunderfish'', under the command of CDR John T. "Pop" Perry (Ward Bond), while on a special mission to the Philippines takes charge of a group of nuns and children, including a newborn infant nicknamed "Butch", transporting them to Pearl Harbor. On their way, the sub sights a Japanese aircraft carrier and attacks, but its torpedoes malfunction, exploding halfway to the target. Pursued by the carrier's escorting destroyers, ''Thunderfish'' manages to escape. While in Pearl Harbor, the ship's Ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Poster
A film poster is a poster used to promote and advertise a film primarily to persuade paying customers into a theater to see it. Studios often print several posters that vary in size and content for various domestic and international markets. They normally contain an image with text. Today's posters often feature printed likenesses of the main actors. Prior to the 1980s, illustrations instead of photos were far more common. The text on film posters usually contains the film title in large lettering and often the names of the main actors. It may also include a tagline, the name of the director, names of characters, the release date, and other pertinent details to inform prospective viewers about the film. Film posters are often displayed inside and on the outside of movie theaters, and elsewhere on the street or in shops. The same images appear in the film exhibitor's pressbook and may also be used on websites, DVD (and historically VHS) packaging, flyers, advertisements in n ...

Salvo
A salvo is the simultaneous discharge of artillery or firearms including the firing of guns either to hit a target or to perform a salute. As a tactic in warfare, the intent is to cripple an enemy in one blow and prevent them from fighting back. Overview Troops armed with muzzleloaders required time to refill their arms with gunpowder and shot. Gun drills were designed to enable an almost continuous rain of fire on the enemy by lining troops into ranks, allowing one rank to fire a salvo, or volley, while the other ranks prepared their guns for firing. The term is commonly used to describe the firing of broadsides by warships, especially battleships. During fleet engagements in the days of sail, from 17th century until the 19th century, ships of the line were maneuvered with the objective of bringing the greatest possible number of cannon to bear on the enemy and to discharge them in a salvo, causing enough damage and confusion as to allow time for the cannon to be sw ...

Leyte
Leyte ( ) is an island in the Visayas group of islands in the Philippines. It is eighth-largest and sixth-most populous island in the Philippines, with a total population of 2,626,970 as of 2020 census. Since the accessibility of land has been depleted, Leyte has provided countless number of migrants to Mindanao. Most inhabitants are farmers. Fishing is a supplementary activity. Rice and corn (maize) are the main food crops; cash crops include coconuts, abaca, tobacco, bananas, and sugarcane. There are some manganese deposits, and sandstone and limestone are quarried in the northwest. Politically, the island is divided into two provinces: (Northern) Leyte and Southern Leyte. Territorially, Southern Leyte includes the island of Panaon to its south. To the north of Leyte is the island province of Biliran, a former sub-province of Leyte. The major cities of Leyte are Tacloban, on the eastern shore at the northwest corner of Leyte Gulf, and Ormoc, on the west coast. Leyte ...

Ramming
In warfare, ramming is a technique used in air, sea, and land combat. The term originated from battering ram, a siege weapon used to bring down fortifications by hitting it with the force of the ram's momentum, and ultimately from male sheep. Thus, in warfare, ramming refers to hitting a target by running oneself into the target. Today, hand-held battering rams are one tool among many used by law enforcement and military personnel for door breaching. Forcible entry by criminals has been implemented using such methods as vehicles rammed into buildings. Naval warfare Navies in antiquity commonly used the ram: the "beak" ( la , rostrum) became an important part of the armament of the galleys of Imperial Rome. The ancient Greeks used their trireme vessels for ramming as well. In ancient China, rams were largely unknown, as the lack of a keel and the flat shape of the junk's bow was not conducive to constructing an elongated underwater spur. The first recorded use of a ram in m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flank Speed
Flank speed is an American nautical term referring to a ship's true maximum speed but it is not equivalent to the term ''full speed ahead''. Usually, flank speed is reserved for situations in which a ship finds itself in imminent danger, such as coming under attack by aircraft. Flank speed is very demanding of fuel and often unsustainable because of propulsion system limitations. The related term emergency may not be any faster than flank but it indicates that the ship should be brought up to maximum speed in the shortest possible time. Other speeds include ''one-third'', ''two-thirds'', ''standard'' and ''full''. One-third and two-thirds are the respective fractions of standard speed. Full is greater than standard but not as great as flank. In surface ship nuclear marine propulsion, the difference between full speed and flank speed is of lesser significance, because vessels can be run at or very near their true maximum speed for a long time with little regard for fuel expended, ...

Fire At Will
Weapons Tight is a NATO brevity code "weapon control order" used in anti-aircraft warfare, imposing a status whereby weapons systems may only be fired at targets confirmed as hostile. Compare to Weapons Hold, whereby it is ordered that weapons may only be fired at targets (especially aircraft or missiles) when under attack, or in response to a formal order; also compare to Weapons Free, which denotes an order that weapons may be fired at targets ''not'' positively identified as friendly. (The latter term should not be confused with the expression denoting areas without weapons in them, particularly ''Nuclear-weapon-free zone A nuclear-weapon-free zone (NWFZ) is defined by the United Nations as an agreement that a group of states has freely established by treaty or convention that bans the development, manufacturing, control, possession, testing, stationing or transpo ...s''.)

Heavy Machine Guns
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber ( 12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/ fortifications beyond the standard-cal ...

Anti-aircraft Guns
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

Deck Guns
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret. The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute. Some submarines also had additional deck guns like auto-cannons and machine guns for anti-aircraft defense. While similar unenclosed guns are often found on surface warships as secondary or defensive armament (such as the US Navy's 5-inch (127 mm)/25 caliber gun which was removed from battleships to mount on submarines), the term "deck gun" normally re ...

Crash Dive
A crash dive is a maneuver by a submarine in which the vessel submerges as quickly as possible to avoid attack. Crash diving from the surface to avoid attack has been largely rendered obsolete with the advent of nuclear-powered submarines, as they normally operate submerged. However, the crash dive is also a standard maneuver to avoid a collision. A crash dive in a diesel-powered submarine requires careful orchestration of the crew. On German U-boats of World War II, a crash dive began with the Captain or senior lookouts giving the order "Alarm!" which led to a bridge officer activating the alarm bell. All crew members then immediately stopped what they were doing and proceeded to their diving stations. Once the lookouts were below deck and the upper deck hatch was secured, the Captain or Chief Engineer shouted the order, "Fluten" ("flood the tanks"). With the bow planes at a maximum down angle, the crew then flooded the forward ballast tanks. Often, all available crew members mo ...

Q-ship
Q-ships, also known as Q-boats, decoy vessels, special service ships, or mystery ships, were heavily armed merchant ships with concealed weaponry, designed to lure submarines into making surface attacks. This gave Q-ships the chance to open fire and sink them. The use of Q-ships contributed to the abandonment of cruiser rules restricting attacks on unarmed merchant ships and to the shift to unrestricted submarine warfare in the 20th century. They were used by the British Royal Navy and the German ''Kaiserliche Marine'' during the First World War and by the Royal Navy, the '' Kriegsmarine'', and the United States Navy during the Second World War (1939–45). Etymology Short for Queenstown in Ireland, as Haulbowline Dockyard in Cork Harbour was responsible for the conversion of many mercantile steamers to armed decoy ships in World War One, although the majority appear to have been converted in larger navy yards such as Devonport.
