USS ''St. Mary's River'' (LSM(R)-528) was originally authorized as ''LSM-528''. Reclassified ''LSM(R)-528'' on 21 April 1945, she was laid down on 19 May 1945 at the Brown Shipbuilding Co., Inc., Houston, Texas, launched on 16 June 1945, and commissioned on 2 September 1945. On 6 September, ''LSM(R)-528'' sailed for Galveston, Texas, arriving the next day. She sailed for Charleston, South Carolina, on 12 September. However, after two days at sea, she ran into a storm and was diverted to Naval Frontier Base, Burrwood, Louisiana. After the storm, ''LSM(R)-528'' resumed her voyage and arrived at Charleston on 21 September. While there, the ship had her rocket launchers and mortars installed. Departing Charleston on 12 October, ''LSM(R)-528'' sailed for Little Creek, VA, arriving on 14 October. After leave and upkeep, she began shakedown training on 15 October.

Brown Shipbuilding Company
The Brown Shipbuilding Company was founded in Houston, Texas, in 1942 as a subsidiary of Brown and Root (now KBR) by brothers Herman and George R. Brown to build ships for the U.S. Navy during World War II. Brown Shipbuilding Company ranked 68th among United States corporations in the value of World War II military production contracts. In 1941, Navy officials asked the Brown brothers to build four submarine chasers. The brothers had no shipbuilding experience, but had helped build Naval Air Station Corpus Christi. In 1942, the brothers formed Brown Shipbuilding and, with $9 million in Navy funding, built the Green's Bayou Fabrication Yard at the juncture of the Houston Ship Channel and Green's Bayou. After delivering the ships, Brown received orders for landing craft and more sub chasers, and eventually won an order for destroyer escorts at $3.3 million per ship. Between May 1943 and August 1944, Brown turned out 61 destroyer escorts, an average of one per week. Perhaps the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

5"/38 Caliber Gun
The Mark 12 5"/38 caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on , commissioned in 1934, the first new destroyer design since the last ''Clemson'' was built in 1922. The base ring mount, which improved the effective rate of fire, entered service on , commissioned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seeba ...

Green Cove Springs, FL
Green Cove Springs is a city in and the county seat of Clay County, Florida, United States. The population was 5,378 at the 2000 census. As of 2010, the population recorded by the U.S. Census Bureau was 6,908. The city is named after the portion of the St. Johns River upon which it is built. The river bends here, and the area is sheltered by trees that are perennially green. History The area was first inhabited over 7,000 years ago by Native Americans by the warm mineral spring. The hydrological spring of the same name, locally known as the "Original Fountain of Youth", attracted guests in the 19th century; more than a dozen hotels were near the spring. Today, the sulfur-scented spring water feeds an adjacent public swimming pool before flowing the short distance to the St. Johns River. The Green Cove Springs area was first developed by George J. F.
