1. Gathering Pertinent Information. The history of the Applied Physics Laboratory between mid-1948 and mid-1956 was characterized by significant technological achievement, an outstanding part of which was the successful development of the missile named Terrier I. This was the first sea-going antiaircraft guided missile in world history. The Laboratory had, prior to that time, pursued an exploratory research and development program that resulted in, among other things, a supersonic-missile, test vehicle configuration. The Navy decided to adapt it to tactical use as a rocket-propelled surface-to-air missile for the Fleet. This decision was communicated to the Guided Missiles Committee of the Department of Defense Research and Development Board on June 11, 1948. Dr. R. B. Kershner of APL proposed the name "Terrier" for the new missile, after These historical notes are adapted from a chapter on the Terrier missile prepared by Rear Admiral M. R. Kelley, U.S. 'avy (Ret. ) for inclusion in a history of the Applied Physics Laboratory. 18 the canine breeds of relatively small size, aggressive and tenacious by nature, but readily controlled by their masters. This name was approved by the Chief of the Bureau of Ordnance on December 29, 1948. Development of Terrier presented no major problem in propulsion because enough was known of rocket propellants to afford confidence that it could attain the speed, altitude, and range d emended.[1] However, there were other problems. Even though roll stabilization- a prerequisite of good beam-riding - had been achieved earlier by both subsonic and supersonic test models, and satisfactory beam-riding had already been demonstrated, unexpected difficulties were encountered in the first two STV*-3 flight tests (April and July, 1948 ) . These tests had among their principal objectives the measurement of roll moment and determination of the damping coefficient, information that was urgently needed before a * Supersonic test vehicle. M. R. Kelley vehicle that incorporated a device for roll stabilization could be tested. Neither test provided the desired data because of malfunctions in the t telemetering equipment, cause unknown. In October 1948, a third test having these same objectives produced good roll data. Confirmatory results were also obtained in another flight test a month later. Shortly thereafter flights of two modified STV-3's, which were intended to be roll-stabilized, proved unsuccessful because of an apparent electrical power failure in one case and, in the other, the occurrence of large acceleration forces at end of boost, which were shown III post-flight analysis to have been present also in two previous STV-3 tests.[2]

agni 5

India successfully test-fired its indigenously developed nuclear capable long range ballistic missile Agni-5 with a strike range of 5,000 km. [5]

helina 2. HELINA is helicopter launched version known of NAG ATGM, designed and developed indigenously for Indian Army under integrated guided missile development program. It is manufactured by India’s sole missile producer, state-owned Bharat Dynamics ltd. It works on the principle of “fire and forget”. It has operational range upto 7-10km.[7]

Brahmos is supersonic cruise missile developed by Brahmos Aerospace, a joint-venture between Russia’s Mashinostroyenia and India’s Defense Research and development organization(DRDO).[9]

Working principle

1.Fire and forget:* Fire-and-forget is a type of missile guidance which does not require further guidance after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, ) is vulnerable to attack and unable to carry out other tasks.[10]

2.Command to Line-Of-Sight (CLOS) The CLOS system uses only the angular coordinates between the missile and the target to ensure the collision. The missile is made to be in the line of sight between the launcher and the target (LOS), and any deviation of the missile from this line is corrected. Since so many types of missile use this guidance system, they are usually subdivided into four groups: A particular type of command guidance and navigation where the missile is always commanded to lie on the line of sight (LOS) between the tracking unit and the aircraft is known as command to line of sight (CLOS) or three-point guidance. That is, the missile is controlled to stay as close as possible on the LOS to the target after missile capture is used to transmit guidance signals from a ground controller to the missile.[11]

3. Active homing Active homing uses a radar system on the missile to provide a guidance signal. Typically, electronics in the missile keep the radar pointed directly at the target, and the missile then looks at this "angle" of its own centerline to guide itself. Radar resolution is based on the size of the antenna, so in a smaller missile these systems are useful for attacking only large targets, ships or large bombers for instance. Active radar systems remain in widespread use in anti-shipping missiles.[12]

Working It’s a missile Tank, this is a Remote Control missile Launcher , Barreled with a Operating system from 6 DC motors power is perfect, it active It's great, this Tank rocket launcher is a very powerful, remote-controlled weapon that exploded and rocketed off very well ... and it also spins 360 degrees easily. It is made from ping pong ball and cardboard with 6 DC motors, Remote Control circuit and some other things.[13]
