Supermarine Seafire
The Supermarine Seafire is a naval version of the Supermarine Spitfire fighter adapted for operation from aircraft carriers. It was analogous in concept to the Hawker Hurricane variants#Sea Hurricanes, Hawker Sea Hurricane, a navalised aircraft, navalised version of the Spitfire's stablemate, the Hawker Hurricane. The name Seafire was derived from the contraction of the full name of Sea Spitfire.Andrews and Morgan 1987, p. 247. A carrier-capable version of the Supermarine Spitfire had been proposed by the British Admiralty, Admiralty in May 1938. Despite a pressing need to replace various obsolete types in the Fleet Air Arm (FAA), some opposed the idea, including Winston Churchill, although these disputes were often a result of the overriding priority for land-based Spitfires instead. During 1941 and early 1942, the Admiralty again requested naval Spitfires, resulting in an initial batch of Seafire Mk.Ib fighters in late 1941, which were mainly used to gain experience operating ...

Bioluminescence
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. Bioluminescence occurs in multifarious organisms ranging from marine vertebrates and invertebrates, as well as in some Fungus, fungi, microorganisms including some bioluminescent bacteria, Dinoflagellate, dinoflagellates and terrestrial arthropods such as Firefly, fireflies. In some animals, the light is bacteriogenic, produced by symbiosis, symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In most cases, the principal chemical reaction in bioluminescence involves the reaction of a substrate called luciferin and an enzyme, called luciferase. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin or Vargulin, cypridina luciferin. In all characterized cases, the enzyme Catalysis, catalyzes the Redox, oxidation of the luciferin resultin ...

Naval Radar
This is a list of different types of radar. Detection and search radars Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The radio waves are usually less than a meter long. Ships and planes are metal, and reflect radio waves. The radar measures the distance to the reflector by measuring the time of the round trip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the ''range gate''. The radar determines the direction because the short radio waves behave like a search light when emitted from the reflector of the radar set's antenna.
