North Korea’s Latest Missile Test

Various sources are reporting that North Korea test-launched two ballistic missiles tonight on lofted trajectories.

One of the missiles is reported to have reached a maximum altitude of 910 km (570 miles) and splashed down at a range of 450 km (280 miles) from the launch point. This missile would have had a burnout speed of about 3.74 km/s with a loft angle of 81.5 degrees, and a flight time of about 17 minutes.

If flown on a standard trajectory with the same payload, that missile would have a maximum range of about 1,900 km (1,200 miles).

This would classify the missile as medium range (1,000 to 3,500 km).

The United States and China Should Start Over

Chinese Communist Party leader Mao Zedong prepares to proclaim the establishment of the People’s Republic of China in Beijing on 1 October 1949.

President Trump’s trade war is demolishing US–China relations. The presidential candidates, Congress and now General Mattis are all lending a hand. Before long the entire economic, social and cultural infrastructure erected after the United States recognized the People’s Republic in 1979 will be a pile of rubble. Read more >

The Congressional defense budget process is entering its conclusion, though battles remain. Despite little to show for it, the overall budget for missile defense continues to be robust. For example, the Senate appropriators met last week and added $1.2 billion above the Trump administration’s budget request for missile defense, including an additional $532 million for upgrades and six more boosters for the beleaguered Ground-based Midcourse Defense system, and added $222 million to fund program to replace the recently canceled Redesigned Kill Vehicle program. That is an unfortunate waste of tax dollars.

However, in other areas Congress—in particular the House—made a number of useful and positive corrections to the administration’s $9.4 billion missile defense budget request. The House also put several sensible new missile defense policies in place that deserve support. Read more >

“More Nukes” Will Not Make Anyone Safer

The New York Times found an odd way to commemorate this year’s anniversaries of the Hiroshima and Nagasaki nuclear bombings—by publishing on August 9 an opinion piece by columnist Bret Stephens titled “The U.S. Needs More Nukes.” Matt Korda has a nice article about it in the Bulletin of the Atomic Scientists. I wanted to add a few comments of my own. Read more >

Why Did the Pentagon Conduct a Treaty-Violating Test?

, co-director and senior scientist

August 21, 2019 10:22 AM EDT

On Sunday, the Pentagon announced that it had launched a Tomahawk cruise missile with a range “more than 500 kilometers” from a ground-based launcher at a test site in California.

The purpose, it said, was to use “data collected and lessons learned from this test” to “inform the Department of Defense’s development of future intermediate-range capabilities.”

The real purpose of the test, however, appears to be to underscore the US decision to leave the Intermediate-range Nuclear Forces (INF) Treaty by conducting a launch that would violate the terms of the treaty. INF prohibited all US and Russian land-based missiles, or launchers for those missiles, with ranges between 500 and 5,500 km. Read more >
