The United States cannot sustain the high cost of the Ballistic Missile Defense System (BMDS) to take out adversaries’ relatively inexpensive missiles, US Northern Command (NORTHCOM) Commander Adm. William Gortney said in congressional testimony on Thursday

WASHINGTON (Defense News) — US adversaries are developing "relatively inexpensive technologies," such as long-range cruise missiles and road-mobile intercontinental ballistic missiles that can reach the US homeland, Gortney explained. "By contrast, our interceptors are vastly more expensive.""Today, our BMDS is in an unsustainable cost model, which has us postured to shoot down inexpensive rockets with very expensive ones," Gortney told to the Senate Armed Services Committee.
The United States is currently working to reduce the costs of missile defense, including improving sensors used to detect incoming missiles, the development of the multiple-object kill vehicle, a single interceptor missile capable of engaging and destroying multiple targets, and directed energy weapons.
By the end of 2017, US homeland missile defense will be comprised of 44 interceptor missiles, when the final 14 are installed in Alaska.

Iran has test-fired several ballistic missiles from silos across the country, the Revolutionary Guard reported. The US has previously imposed missile-related sanctions against Tehran over the testing of the new intermediate-range Emad ballistic missile.

The test on Tuesday was intended "to show Iran's deterrent power and also the Islamic Republic's ability to confront any threat against the Revolution, the state and the sovereignty of the country," the Islamic Revolutionary Guard Corps statement published on its website said.

The Revolutionary Guard and the Iranian media did not specify which missiles were used in the test. The underground silos in Iran were first revealed to the public in October 2015, almost coinciding with the revelation of the Emad ballistic missile, and were said to be capable of firing "Iranian missiles of varying ranges.” Iranian news channel Press TV used archive footage of an October test of the Emad missile when reporting the Tuesday test.
The Emad missile is believed to be developed from Iran’s Shahab-3 missile. It is a liquid-propellant ballistic missile with a claimed range of 1,700km and a 750 kg payload. The missile’s primary improvement is said to be a better guidance system of the re-entry vehicle, reportedly reaching an accuracy of 500 meters.
The test in October was condemned by the US and its allies, with Washington saying the missile was “inherently capable of delivering a nuclear weapon,” and that testing it violated UN Security Council Resolution 1929. Tehran denied the allegation, saying it has never tried to develop a nuclear weapon and hasn’t designed any of its missiles to carry one.
The resolution tackled Iran’s controversial nuclear program and was among those which expired in January, when the UN’s nuclear watchdog the IAEA confirmed Tehran’s compliance with the terms of a nuclear deal it struck last year with six leading world powers. In October, at the time of testing, the resolution was still in force.
The UNSC has since adopted another resolution, which called upon Iran not to undertake any work on missiles "designed to" deliver nuclear weapons.
Iran is currently undergoing a political transition, with President Hassan Rouhani and his allies securing in an election in February a majority of seats at the Assembly of Experts – the body tasked with electing the Supreme Leader of Iran, the most powerful figure in the country. The seat is now held by 76-year-old Ayatollah Ali Khamenei.
Some Iran watchers said that after the Rouhani-sponsored nuclear deal turned out to be a success, the conservative camp insisted on a demonstration of force to reassert Iran’s strength.
