Patriot Missile Air Defence System (MIM-104 Patriot)

Patriot Missile Air Defence System. it's a long-range, all-altitude, all-weather, air defence system. is a surface to air missile (SAM) system. Patriot Missile Air Defence System is manufactured by the Raytheon Company. Patriot Missile Air Defence System have been sold to many counties in the world such as Taiwan, Greece, Israel, Egypt, Germany, Japan, Kuwait, Netherlands, Saudi Arabia, and United Arab Emirates, and Spain. This missile can defeats advanced threats, including aircraft, tactical ballistic missiles, cruise missiles and UAVs

Patriot uses an advanced aerial interceptor missile and high performance radar systems. the major functional functions that MIM-104 Patriot has are communications, command and control, radar surveillance, and missile guidance. the combinatin of those four functions provides integrated, mobile air defense system.

MIM-104 Patriot is modular and highly mobile. all the components are trailer-mounted. the components are radar set, engagement control section, antenna mast group, electric power plant and launcher. so mobile that quite possible to launch this missile every where.

MIM-104 Patriot fire control section,

consisting of the AN/MPQ-53 or -65 Radar Set, the AN/MSQ-104 Engagement Control Station (ECS), the OE-349 Antenna Mast Group (AMG), and the EPP-III Electric Power Plant.

• The AN/MPQ-53 and AN/MPQ-65 Radar Set

is a passive electronically scanned array radar equipped with IFF. electronic counter- countermeasure (ECCM), and TVM guidance subsystems. These radar is unique. A single unit performs all search, identification, track, and engagement functions.

• The AN/MSQ-104 Engagement Control Station

The main sub-components of the Engagement Control Station are the Weapons Control Computer (WCC), the data link terminal (DLT), the communications array, the Routing Logic Radio Interface. The Engagement Control System is fully shielded to against electronic interferences.

• The OE-349 Antenna Mast

GroupOE-349 Antenna Mast Group. includes four 4 kw antennas in two pairs on remotely controlled masts. Mounted at the base of each pair of antennas two high power amplifiers associated with the antennas and the radios collocated shelter. It is through these antennas that the ECS and ICC send their respective UHF "shots" to create PADIL nerwork.

• The EPP-III Electric Power Plant

EPP-III diesel-electric Power Plant (EPP) is the power source for the ECS and radar. EPP consist of two kilowatt diesel engines with 400Hz generators that are interconnect through the power distribution unit. The generators are mounted on a modified M977 HEMTT. Each EPP has 75-gallon fuel tanks and a fuel distribution assembly with grounding equipment. Each diesel engine can operate more than a fuel distribution assembly with grounding equipment. Each diesel engine can operate more thatn 8 hours with a full fule tank. The EPP delivers its power to the radar and ECS through cables stored in reels alongside the generators

TVM in patriot missile

the patriot missile is equipped with a track-via-missile (TVM) guidance system. Midcourse correction commands are transmitted to the guidance system from the mobile engagement control centre. The target acquisition system in the missile acquires the target in the terminal phase of flight and transmits the data using TVM downlink via the ground radar tothe engagement control station for final course correction calculations. The course correctioncommands are transmitted to the missile via missile track command uplink.

BATTLE of IWO JIMA

iwo jima battle is a battle between US and Japan during February until March 1945 that happened in the 2nd worldwar. the US invasion in in Iwo Jima was charge with the mission of capturing the two airfields on Iwo Jima.

The U.S marine attacked Iwo Jima on 19 Febuary 1945. Iwo Jima Island conquered after the big war on 16 March with the total 110,000 soldier were deployed to attack japanese that only had 18,061-18,375 soldiers in Iwo Jima. there was 6,281 U.S soldier killed and 19,217 U.S soldier wounded but japanese has more losses with 17,845-18,591 soldiers dead and 216 soldier captured. U.S also lost USS Bismarck Sea that sunk in 21 February 1945.

the 10th general Simon Buckner landed along the west coast of Okinawa on 1 April 1945. U.S marine soldiers has fought for 79 days and they only made a 23 km progress. the japanesse counter ended in 21 June. many U.S soldiers dead in this war including the 5th U.S navy. this armada had been attacked by the japanese kamikaze planes. and cause 26 U.S warships sunk.

The Japanesepositions on the island were heavilyfortified, with vastbunkers, hiddenartillery, and 18 km (11 mi) of underground tunnels. Americans were covered by extensive naval and air support, capable of putting an enormous amount of firepower onto the Japanese positions.

The battle was immortalized by Joe Rosenthal's photograph of the raising of the U.S. flag on top of the 166 m (545 ft) MountSuribachi by five Marines and one Navy Corpsman.
