When North Korea said it was going to continue developing nuclear weapon and missile technology regardless of the Iran nuclear deal earlier on Tuesday, most observers probably didn’t expect that the communist state would also install a 67 meter tall launch pad later in the day — its largest on record.

Technically, an extension was built on an existing 50 meter launch pad, but with the extra length, the North will also have the capability to fire missiles with longer ranges.

“We believe that the North will use the extended launch site in Dongchang-ri to fire a long-range missile longer than the Unha-3,” a South Korean government official told Yonhap News Agency. “We think (the North) will carry out a provocation around the 70th anniversary of the foundation of the Workers’ Party on Oct. 10.”

The U.N. Security Council has put a ban on North Korea for testing large-scale missile technology, but the country has violated it on multiple accounts.
