The whole package, including training and support for the missile, is estimated to cost $850 million. The statement said Denmark, the Netherlands, Norway, and the US Foreign Military Financing program would help pay for it. "This proposed sale will improve Ukraine's capability to meet current and future threats by further equipping it to conduct self-defense and regional security missions," the State Department statement said. Congress must still approve the sale for it to be final, though US lawmakers have never successfully blocked such proposed packages.
