10 extremely expensive "iron bird" models of the US

F / A-18 Hornet - US $ 94 million: Launched since the 1980s, this fighter is the first aircraft to attack air and ground targets.It was used during the Gulf War, but it was also purchased by many countries such as Canada, Australia, Finland, Kuwait, Malaysia, Spain and Switzerland.

V-22 Osprey - $ 118 million: This tilt-wing helicopter can take off and land vertically but can fly as fast as a fixed-wing aircraft, used for the first time in combat. in Iraq in 2007. Osprey's production had many problems with design and manufacturing, when it killed at least 30 Marines and civilians in the development phase.However, thanks to the range and versatility of V-22, the Marines put a squadron of aircraft into Afghanistan.

US $ 122 million F-35 Lightning II: Lockheed Martin's contract to build the F-35, the latest stealth fighter aircraft, was the most expensive deal for the US military.The goal of the F-35 is to replace obsolete aircraft and it is part of a multi-functional fighter development program between the United States and its allies.However, it has been criticized for its ability to fight poorly and too badly, making them a target to be easily shot down.Moreover, from 2007 to 2008, network spies have infiltrated the computer system of the development program, but Lockheed Martin said the program was not compromised.

E-2D Advanced Hawkeye - US $ 232 million : Considered the biggest step of military reconnaissance technology, Advanced Hawkeye's radar system has increased the tracking of aircraft operation by more than 300% compared to aircraft. other.An analyst once commented that 'it can see chestnuts peeling off shells in Iran'.After a long trial process, E-2D has been officially put into operation since October last year.

VH-71 Kestrel - 241 million USD: The project to produce this high-tech aircraft to replace the presidential helicopter fleet is becoming obsolete, but it has exceeded 50% of its budget. early when President Barack Obama took office.Initially, Mr. Obama made a decision to cancel the project due to exceeding the budget, but it was agreed that the US Senate Budget Distribution Committee had agreed to spend $ 485 million on this project.

B-2 Spirit - $ 2.4 billion : B-2 bombers were so expensive that the US Congress had to cut the number of aircraft ordered from 132 to 21.B-2 is a bombardment that is difficult to detect through infrared signals, sound, electromagnetic fields, radar or the naked eye.Its invisibility makes it less risky to bomb enemy targets.Introduced in 1993, B-2 has been deployed to Iraq and Afghanistan.
