How INS Arihant could be a game changer in the region?

New Delhi: The indigenous nuclear submarine INS Arihant is set to be launched for sea trials in a "month or two" and it will test-fire the submarine-launched nuclear capable ballistic missile BO-5, DRDO said today.

The nuclear reactor on board the INS Arihant was activated last year in August taking it closer towards sea trials after which the vessel would be inducted into operational service in the Navy.

"Arihant is going through the power-up cycle (in its nuclear reactor). It is the first time that we are doing the power-up cycle on a nuclear submarine. So, we are very cautious and going step by step. It will take a month or two more before it goes to the sea (for trials)," DRDO chief Avinash Chander told PTI.
He was asked about the present status of the indigenous nuclear submarine programme under which at least three Arihant-Class nuclear underwater vessels would be built for the Navy.

"During the trial phase, the Arihant will testfire the fully-developed BO-5 missile as part of the sea trials," he said.
Once inducted, the submarine will help the country complete its nuclear triad giving it the capability to respond to nuclear strikes from sea, land and air-based systems.
Nuclear triad is the ability to fire nuclear-tipped missiles from land, air and sea-based weapon platforms.
INS Arihant has been undergoing trials at Navy's key submarine base in Vishakhapatnam and has cleared most of its harbour acceptance trials.
The medium-range nuclear missile BO-5 has a range of over 700km-range.
The nuclear submarine will help India achieve the capability of going into high seas without the need to surface the vessel for a long duration.

Conventional diesel-electric submarines have to come up on surface at regular intervals for charging the cells of the vessel.

Top eight special forces in the world !

Top Ten Special Forces in the world !

For Details study Wikipedia 

Today we gonna tell you about the world's best special forces ever. Special Forces are required for the special operations. For example during the mumbai attacks in India 2008. Special Forces of India perform the action and killed the terrorists and caught up the one terrorist alive named Ajmal Kasab.

Countries throughout the world train special operation forces within their military, so coming up with a list of top special operations forces in the world is difficult at best. 

                                                      

 All special ops forces train their military men to be the best of the best, to take the impossible task and make it possible.  In that respect, all Special Operations units are top.  Special forces, or special operations forces are military units extremely trained to perform unconventional, typically insecure missions for a nation’s political, economic or military purposes. 

Here is the list of top 8 Special Forces of the world !

8. MARCOS (INDIA)

                                 

The MARCOS (Marine Commando Force) is an elite special operations unit of the Indian Navy. It was created for conducting special operations such as Amphibious warfare, Counter-terrorism, Direct action, Special reconnaissance, Unconventional warfare, hostage rescue, Personnel recovery, Asymmetric warfare, Counterproliferation. The MARCOS is specially organised, trained and equipped for the conduct of special operations in a maritime environment. It is recently active in Indian Ocean to protect their homeland.

7. SSG (PAKISTAN)

                      

The SSG (Special Services Group) is a special operations force of the Pakistan Army. It is quite similar to the U.S. Army’s Special Forces and the British Army’s SAS. The unit was created in 1956, it also known as “Black Storks” a name derived from their unique headgear the “Maroon Beret”. The SSG considered one of the world’s best special forces because of their courage and bravery. As a Russian president once said that if he had Pakistan’s army and Russian weapons he could conquer all the world because they are very brave. 

6. NSG (INDIA)

                           

   
The National Security Guard (NSG) is one of the eight Central Armed Police Forces of India raised "for combating terrorist activities with a view to protect States against internal disturbances".^[1] It is one of the eight Central Armed Police Forces under the Government of India, Ministry of Home Affairs. The NSG has two components, the Special Action Group (SAG), which consists entirely of army personnel; and the Special Ranger Groups (SRG), which comprises personnel drawn from the other Central Armed Police Forces and State Police Force. The head of the force, designated as a Director General, who wears the same badges of ranks as an army Lieutenant General, is an officer from the Indian Police Service^.

5. JW GROM, Poland

                          

The JW GROM (Jednostka Wojskowa GROM) is Poland’s elite counter-terrorism unit. The unit was officially activated on July 13, 1990 in response to terrorist threats. GROM, which stands for “thunder” is one of the five special operation forces units of the Polish Armed Forces. They are trained to respond to a variety of threats and unconventional warfare roles, including anti-terrorist actions and projection of power behind enemy lines.

4. GSG 9, Germany

                    
GSG 9 is a German counter-terrorism and special operations unit of the German Federal Police. It was officially established in 1973 after the mismanagement of the German Police to successfully free 11 Israeli athletes who were kidnapped in Munich during the Summer Olympic Games. GSG 9 is deployed in cases of hostage taking, kidnapping, terrorism and extortion. It also be used to secure locations, neutralize targets, track down fugitives and sometimes conduct sniper operations. The unit is very active in developing and testing methods and tactics for these missions. From 1972 to 2003 they reportedly completed over 1,500 missions,[1] discharging their weapons on only five occasions.

3. Delta Force, United States

                     
1st Special Forces Operational Detachment-Delta (1st SFOD-D), popularly known as Delta Force, was officially approved in 1997 after numerous, well-publicized terrorist incidents in USA. It’s the best and one of the most secretive forces in the US. Modeled after the British 22 Special Air Service Regiment, or SAS. The founder/co-founder of SFOD-D was a former SAS operative who thought the US needed an elite force like the SAS. Delta Force’s primary tasks are counter-terrorism, direct action, and national intervention operations, although it is an extremely versatile group capable of conducting many types of clandestine missions, including, but not limited to, hostage rescues and raids.

2. Navy SEALs, United States

                      
The Navy SEALs, also known as the United States Navy’s Sea, Air and Land Teams can trace their roots to World War II. SEALs are male members of the United States Navy, and are one of the United State’s most elite special Warfare Combatants. The CIA’s highly secretive Special Activities Division (SAD) and more specifically its elite Special Operations Group (SOG) recruits operators from the SEAL Teams. Joint Navy SEALs and CIA operations go back to the famed MACV-SOG during the Vietnam War. This cooperation still exists today and is seen in the wars in Iraq and Afghanistan. Most recent joint Navy SEALs and CIA operation in the finding and killing of Osama bin Laden in Pakistan.

Comparison of India and pakistan on the basis of weapons ?

Comparison of India and Pakistan on the basis of weapons !

India and Pakistan have long engaged in wars, largely due to a territorial dispute in the Kashmir region. Originally, the conflict began when the subcontinent was divided after World War II for the sole purpose of separating Muslims from the Hindus. However, this division was not as effective as it was foreseen, and the long and bloody series of the Indo-Pakistani conflicts began.

In almost all aspects, India holds the upper hand; numerically, technologically, and economically, India is significantly superior to Pakistan. India is the world’s number one buyer of arms and weapons from a variety of contractors and manufacturers from the US, UK, China, Russia, and several others.

Technology Behind the Guided Missiles !

Technology Behind the Guided Missile System !

                                

Liftoff of Missile.

        Missiles are generally categorized by their launch platform and intended target. In broadest terms, these will either be surface (ground or water) or air, and then sub-categorized by range and the exact target type (such as anti-tank or anti-ship). Many weapons are designed to be launched from both surface or the air, and a few are designed to attack either surface or air targets (such as the adats missile). Most weapons require some modification in order to be launched from the air or surface, such as adding boosters to the surface-launched version.

 

 

 

 

Various Components of a missile :-

There are different components which are used by a missile to reach its target are given below:-

• Targeting and/or guidance system
• Flight system
• Engine
• Warhead   
  
                    
   
  
  
  
  

Guidance system

Missiles may be targeted in a number of ways. The most common method is to use some form of radiation, such as infrared, lasers or radio waves, to guide the missile onto its target. This radiation may emanate from the target (such as the heat of an engine or the radio waves from an enemy radar), it may be provided by the missile itself (such as a radar) or it may be provided by a friendly third party (such as the radar of the launch vehicle/platform, or a laser designator operated by friendly infantry). The first two are often known as fire-and-forget as they need no further support or control from the launch vehicle/platform in order to function. Another method is to use a TV camera—using eithervisible light or infra-red—in order to see the target. The picture may be used either by a human operator who steers the missile onto its target, or by a computer doing much the same job. One of the more bizarre guidance methods instead used a pigeon to steer the missile to its target.

Many missiles use a combination of two or more of the above methods, to improve accuracy and the chances of a successful engagement.

Targeting system

Another method is to target the missile by knowing the location of the target, and using a guidance system such as INS, TERCOM or GPS. This guidance system guides the missile by knowing the missile's current position and the position of the target, and then calculating a course between them. This job can also be performed somewhat crudely by a human operator who can see the target and the missile, and guides it using either cable or radio based remote-control, or by an automatic system that can simultaneously track the target and the missile. Furthermore, some missiles use initial targeting, sending them to a target area, where they will switch to primary targeting, using either radar or IR targeting to acquire the target.

Flight system

Whether a guided missile uses a targeting system, a guidance system or both, it needs a flight system. The flight system uses the data from the targeting or guidance system to maneuver the missile in flight, allowing it to counter inaccuracies in the missile or to follow a moving target. There are two main systems: vectored thrust (for missiles that are powered throughout the guidance phase of their flight) and aerodynamic maneuvering (wings, fins, canards, etc.).

Engine

Missiles are powered by an engine, generally either a type of rocket or jet engine. Rockets are generally of the solid fuel type for ease of maintenance and fast deployment, although some larger ballistic missiles use liquid fuel rockets. Jet engines are generally used in cruise missiles, most commonly of the turbojet type, due to its relative simplicity and low frontal area. 

 Turbofans and ramjets are the only other common forms of jet engine propulsion, although any type of engine could theoretically be used. Missiles often have multiple engine stages, particularly in those launched from the surface. These stages may all be of similar types or may include a mix of engine types - for example, surface-launched cruise missiles often have a rocket booster for launching and a jet engine for sustained flight.

                                           

Warhead

Missiles generally have one or more explosive warheads, although other weapon types may also be used. The warhead or warheads of a missile provides its primary destructive power (many missiles have extensive secondary destructive power due to the high kinetic energy of the weapon and unburnt fuel that may be on board). Warheads are most commonly of the high explosive type, often employing shaped charges to exploit the accuracy of a guided weapon to destroy hardened targets. Other warhead types include submunitions, incendiaries, nuclear weapons, chemical, biological or radiological weapons or kinetic energy penetrators. Warheadless missiles are often used for testing and training purposes.
