With just three weeks left before US president-elect Donald Trump takes office, the administration of US president Joe Biden is rushing to supply Ukraine with as many weapons as possible, reports The Telegraph.

Biden is obviously worried that Trump will do what he has threatened to do—and reduce or end US aid to Ukraine.

The Ukrainian government isn’t taking any chances. It’s hurrying to develop weapons it can build, pay for, and use all on its own.

It is about the basic Trembita missile, under development since 2023, and costs only $10,000.

PARS, the Ukrainian firm that builds the Trembita, is working on a bigger, farther-flying version that should be able to reach Moscow, 400 miles from the Ukrainian border.

That version, which should be ready in around a year, would undoubtedly cost more than $10,000—but would still be potentially the cheapest deep-strike munition in the world. An ATACMS costs more than $1 million.
