In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were originally conceived in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied.
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war.
The Hellenic Navy is the naval force of Greece, part of the Hellenic Armed Forces. The modern Greek navy historically hails from the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy it was known as the Royal Hellenic Navy.
A littoral combat ship (LCS) is either of two classes of relatively small surface vessels designed for near-shore operations by the United States Navy. It was "envisioned to be a networked, agile, stealthy surface combatant capable of defeating anti-access and asymmetric threats in the littorals", although their ability to perform these missions in practice has been called into question.
The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican, UAE, and United States navies. It was originally intended and used primarily as a point-defense weapon against anti-ship missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. The rolling interferometer permits the antennas to look at all planes of incoming energy. In addition, because the missile rolls, only one pair of steering canards is required. As of 2005, it is the only U.S. Navy missile to operate in this manner.
The Romanian Naval Forces is the principal naval branch of the Romanian Armed Forces and operates in the Black Sea and on the Danube. It traces its history back to 1860.
The Royal Malaysian Navy is the naval arm of the Malaysian Armed Forces. RMN is the main agency responsible for the country's maritime surveillance and defence operations. RMN's area of operation consists of 603,210 square kilometers covering the country's coastal areas and Exclusive Economic Zones (EEZ). RMN also bears the responsibility of controlling the country's main Sea Lines of Communications (SLOC) such as the Straits of Malacca and the Straits of Singapore and also monitors national interests in areas with overlapping claims such as in Spratly.

The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval autocannon built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales.
The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities. In recent times, Australia released its Surface Fleet Review in 2024, which analyses the future of the RAN and shows what the Government will procure.
The Egyptian Navy, also known as the Egyptian Naval Forces, is the maritime branch of the Egyptian Armed Forces. It is the largest navy in the Middle East as well as Africa, and is the twelfth largest navy in the world. The navy protects more than 2,000 kilometers of coastline of the Mediterranean Sea and the Red Sea, defense of approaches to the Suez Canal, and it also supports for army operations. The majority of the modern Egyptian Navy was created with the help of the Soviet Union in the 1960s. The navy received ships in the 1980s from China and Western sources. In 1989, the Egyptian Navy had 18,000 personnel as well as 2,000 personnel in the Coast Guard. The navy received ships from the US in 1990. US shipbuilder Swiftships has built around 30 boats for the Egyptian Navy including mine hunters, survey vessels, and both steel and aluminium patrol boats.
DARDO originally known as Breda Type-70, also marketed as the OTO Twin 40L70 Compact, is a close-in weapon system (CIWS) built by the Italian companies Breda and Oto Melara. It is composed of two Breda-built Bofors 40 mm firing high explosive (HE) shells, a fire-control radar and a fire-control system. It is the last of a long series of Italian anti-aircraft weapons derived from the Swedish Bofors 40 mm autocannons.
