Although tensions between Washington and Iran have risen, U.S. Defense Secretary Jim Mattis said on Saturday he was not considering raising the number of U.S. forces in the Middle East to address Iran's "misbehavior" at this time, but warned that the world would not ignore Iranian
Iran has one of the Middle East's largest missile programmes and held a similar exercise in December to showcase its defence systems, including radars, anti-missile defence units, and short and medium-range missiles.
Tehran confirmed on Wednesday that it had test-fired a new ballistic missile, but said the test did not breach the Islamic Republic's nuclear agreement with world powers or a U.N. Security Council resolution endorsing the pact.
Iran has test-fired several ballistic missiles since the nuclear deal in 2015, but the latest test was the first since Trump entered the White House.
Trump said during his election campaign that he would stop Iran's missile programme.
The United Nations Security Council held an emergency meeting on Tuesday and recommended the missile testing be studied at committee level. The new U.S. ambassador to the United Nations, Nikki Haley, called the test "unacceptable".
The Security Council resolution was adopted to buttress the deal under which Iran curbed its nuclear activities to allay concerns they could be used to develop atomic bombs, in exchange for relief from economic sanctions.
The resolution urged Tehran to refrain from work on ballistic missiles designed to deliver nuclear weapons. Critics say the resolution's language does not make this obligatory.
Tehran says it has not carried out any work on missiles specifically designed to carry nuclear payloads.
