We’re driven blindfolded to a secret location where Ukraine is making one of its latest weapons.

We’re told to turn off our phones - such is the secrecy around the production of Ukraine’s Flamingo cruise missile.

For Ukraine, dispersing and hiding the production of weapons like this is key to survival. Two factories belonging to the company that makes it - Fire Point - have already been hit.

Even under fire, Ukraine is ramping up its arms industry. President Volodymyr Zelensky says the country now produces more than 50% of the weapons it uses on the front line. Almost its entire inventory of long-range weapons is domestically made.

At the start of the war Ukraine mostly relied on its old Soviet-era arsenal. Western military support helped modernise the country’s armed forces, but it now leads much of the world in developing unmanned systems – like robots and drones.
