The 5th Battalion, 4th Gorkha Rifles, 5/4 GR, the Kannchi Paltan, was raised on 1 January 1963, in the wake of the Chinese Invasion, by Lt Colonel Ranjit Singh Chandel, formerly of 1/4 GR, at Ambala Cantonment, Haryana, the sprawling cantonment town, north of Delhi. In 1988, 5/4 GR celebrated its Silver Jubilee in Naraina, Delhi Cantonment.
In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance. The Mark 46 was initially developed as Research Torpedo Concept I ( RETORC I ), one of several weapons recommended for implementation by Project Nobska , a 1956 summer study on submarine warfare .
Even without knowledge that we are working in the multiplicative group of integers modulo n, we can show that a actually has an order by noting that the powers of a can only take a finite number of different values modulo n, so according to the pigeonhole principle there must be two powers, say s and t and without loss of generality s > t, such that a s ≡ a t (mod n).
The 5-inch (127 mm)/54-caliber (Mk 45) lightweight gun is a U.S. naval artillery gun mount consisting of a 5 in (127 mm) L54 Mark 19 gun on the Mark 45 mount. [1] It was designed and built by United Defense, a company later acquired by BAE Systems Land & Armaments, which continued manufacture.
Then () = means that the order of the group is 8 (i.e., there are 8 numbers less than 20 and coprime to it); () = means the order of each element divides 4, that is, the fourth power of any number coprime to 20 is congruent to 1 (mod 20).
In July 2012, the Mark 38 MGS program was further expanded, resulting in the Mark 38 Mod 3, the latest variant of the system. [5] The Mod 3 is currently being fielded by BAE under a separate program from the TLS program. [3] In FY2019, a Maritime Accelerated Acquisition program was started to procure the Mod 4 variant of the Mark 38.
A new type of 4.5 inch gun with a longer 55-calibre barrel, it was designed in the 1960s for the Royal Navy's new classes of frigates and destroyers.The weapon, built by Vickers Ltd Armament Division, was developed by the Royal Armament Research and Development Establishment using the Ordnance, QF 105 mm L13 of the Abbot self-propelled gun as a starting point (it used electrical primers).
The class was named G 4/5 under the Swiss locomotive and railcar classification system. According to that system, G 4/5 denotes a narrow gauge steam locomotive with a total of five axles, four of which are drive axles. The Rhaetian Railway procured a total of 29 examples of the G 4/5 class between 1904 and 1915.
