In 2017 the government signed a deal with wb Group, a Polish electronics company, to buy supplies of its catapult-launched Warmate loiterer, which has a weight of 5.3kg and a range of 15km—though legal problems interfered with its planned deployment last year, and whether it is now in use is not public information.
2017年，乌克兰政府与波兰电子公司WB Group签署了一项协议，购买Warmate微型巡飞弹设备，该装置重5.3公斤，射程15公里--尽管法律问题干扰了其去年的部署计划，目前尚不清楚它是否已投入使用。

Three other Ukrainian firms—Adrones, cdet and Cobra—are also working on the idea, and although none had a deployable system when the current war started, experience has shown that Ukrainian armourers excel at improvisation and at turning out usable products rapidly in difficult conditions.
其他三家乌克兰公司--Adrones、CDET和Cobra--也在研究这一想法，尽管在当前的战争开始时，没有一家公司拥有可部署的系统，但经验表明，乌克兰的装甲商擅长即兴发挥，可在困难的条件下迅速生产出可用的产品。
