P-800 Oniks

The P-800 Oniks (Russian: П-800 Оникс; English: Onyx), also known in export markets as Yakhont (Russian: Яхонт; English: ruby), is a Soviet / Russian supersonic anti-ship cruise missile developed by NPO Mashinostroyeniya as a ramjet version of P-80 Zubr. Its GRAU designation is 3M55, the air launched Kh-61 variant also exists. The missile has the NATO codename SS-N-26 "Strobile". Development officially started in 1983, and in the 1990s the anti-ship missile was tested on the Project 1234.7 ship. In 2002 the missile passed the whole range of trials and was commissioned. It is reportedly a replacement for the P-270 Moskit, and possibly also of the P-700 Granit.

The missile is carried in flight by aerodynamic lift. The solid-propellant booster is located in the ramjet's combustion chamber and is ejected by the airflow after it has burned out.

Advantages

  • Over-the-horizon firing range
  • Full autonomy of combat use ("fire and forget")
  • A set of flexible ("low-profile sea-skimming", "high-low") trajectories
  • High supersonic speed in all phases of flight
  • Full harmonization for a wide range of platforms (surface ships, submarines and land-based launchers)
  • Possible use of the missile in electronic countermeasures environment and under enemy fire

  The  Mikoyan PAK DP  ( Russian :  ПАК ДП , short for:  Перспективный авиационный комплекс дальнего перехвата ,  romanized :  Perspektivny aviatsionny kompleks dal'nego perekhvata ,  lit.   ''Prospective air complex for long-range interception'') is a Russian programme to develop a  stealth   interceptor aircraft /heavy fighter under development by  Mikoyan [2] [3] [4] [5]  to replace the  Mikoyan MiG-31  in the  Russian Air Force  in mid-2020s or mid-2030s. [6] [7] [8]  It is often referenced as  Mikoyan MiG-41 , because its project code is izd.41, but its official designation has never been given, as Russian planes only get their official designation when they are about to enter service. [9]  According to the Russian defence analyst Vasily Kashin, the MiG-41 would be considered as a 5++ or  6th generation  project. In an interview for Russia Today, the Director General of RSK MiG,...

AN/SEQ-3 Laser Weapon System

  The  AN/SEQ-3 Laser Weapon System  or  XN-1 LaWS [1]  is a  laser weapon  developed by the  United States Navy . The weapon was installed on  USS  Ponce  for field testing in 2014. In December 2014, the United States Navy reported that the LaWS system worked perfectly against low-end  asymmetric  threats, and that the commander of  Ponce  was authorized to use the system as a defensive weapon. The LaWS is a ship-defense system that has so far publicly engaged an  unmanned aerial vehicle  (UAV or drone) and a simulated small-boat attacker. LaWS uses an infrared beam from a  solid-state laser  array which can be tuned to high output to destroy a target or low output to warn or cripple the sensors of a target. One of its advantages over projectile weapons is the low cost per shot: Each firing of the weapon requires only the minimal cost of generating the energetic pulse; by contrast, ordnance f...

M270 Multiple Launch Rocket System

The   M270 Multiple Launch Rocket System   ( M270 MLRS ) is an American   armored ,   self-propelled ,   multiple rocket launcher . The first M270s were delivered to the  U.S. Army  in 1983. The MLRS has since been adopted by several  NATO countries . Some 1,300 M270 systems have been manufactured in the United States and in Western Europe, along with more than 700,000  rockets . Production of the M270 ended in 2003, when a last batch was delivered to the  Egyptian Army . MLRS was developed in 1977–80s jointly by the United Kingdom, United States, West Germany, France and Italy, developed from the older General Support Rocket System (GSRS), and initially fielded in the late 1980s. The M270 MLRS weapons system is collectively known as the M270 MLRS Self-Propelled Loader/Launcher (SPLL). The SPLL is composed of three primary subsystems: the M269 Loader Launcher Module (LLM), which also houses the electronic Fire Control System, is mat...
