Hypersonic missiles

With reference to the Hypersonic missiles, consider the following statements:

1. Hypersonic missiles travel at speeds of at least Mach 5.
2. It cannot manoeuvre mid-flight.

Which of the statements given above is/are correct?

A. 1 only
B. 2 only
C. Both 1 and 2
D. Neither 1 nor 2

Answer: 1 only

Explanation: Kim Jong Un personally oversaw the successful test of a hypersonic missile and urged North Korea to press ahead with building more “strategic military muscle” despite international sanctions over its nuclear weapons programme.

Hypersonic missiles are listed among the “top priority” tasks for strategic weapons development in North Korea’s five-year plan.

It was the third reported North Korean test of a hypersonic gliding missile. The missile flew 700 kilometres (435 miles) at an altitude of about 60 kilometres (37 miles) at Mach 10 speed.

The most recent test demonstrated “the superior manoeuverability of the hypersonic glide vehicle”. It also claimed it accurately hit a target some 1,000 kilometers (620 miles) away.

South Korea’s military, which had cast doubt on Pyongyang’s initial claims, said the missile launched recently had reached hypersonic speeds and showed clear signs of “progress” from last week’s test.

Hypersonic missiles travel at speeds of at least Mach 5 — five times the speed of sound — and can manoeuvre mid-flight, making them harder to track and intercept.
