A network of secret weapons factories has been built in Ukraine, some of which are underground, while others are "hidden under huge decorations," according to a source in the Ukrainian arms industry, reports El Mundo daily.

The location of these factories is "top secret," the daily claims.

As per El Mundo’s interlocutor, Ukraine is now most worried about the extent to which these factories are hidden from Russian troops.

"We found some traitors among the workers," added the source.

The interlocutor noted that Ukraine "has what Europe lacks, and Europe has what we lack."

"We are short of money and contracts, but Europe does not have factories that will enable to rearm because of the Russian threat. Here we have the experience and resources to produce what they want in a much shorter time than any other European factory,” says the source.

The Minister of Digital Transformation of Ukraine, Mykhailo Fedorov, said that in 2024, Ukraine increase the production of long-range drones by ten times compared to last year. Most drones have a range of 700 to 1,000 kilometers, but there are models with a range of over 1,000 kilometers.
