What a strange few days for BAE Systems (LSE: BA.<\/a>) shares! The share price has been on the move. It\u2019s up 22%, adding over \u00a310bn to the company\u2019s market cap in less than a month. But it\u2019s recent developments in the Ukraine war that have been making headlines.<\/p>\n In short, it turns out this could be a window into the latest tech coming out of BAE Systems. It might even be a reason the share price is going to continue its hot streak\u2026<\/p>\n Should you buy BAE Systems shares today?\t<\/p>\n Before you decide, please take a moment to review this report first. Despite ongoing uncertainties from US tariffs to global conflicts, Mark Rogers and his team believe many UK shares still trade at substantial discounts, offering savvy investors plenty of potential opportunities to learn about.<\/p>\n That\u2019s why this could be an ideal time to secure this valuable research \u2013 Mark\u2019s analysts have scoured the markets to reveal 5 of his favourite long-term \u2018Buys\u2019. Please, don\u2019t make any big decisions before seeing them.<\/p>\n What happened?<\/p>\n So what happened? Basically, reports emerged that drones designed and manufactured by the UK are being used by Ukraine in the conflict. <\/p>\n The salient detail is that Nyan drones are produced by Callen-Lenz, a fully owned subsidiary of BAE Systems that manufactures them in Wiltshire, England. In other words, the FTSE 100 defence firm produces some of the Unmanned Aerial Vehicles (UAVs) that Ukraine is using.<\/p>\n Nyan is just one part of BAE Systems\u2019 portfolio of uncrewed air systems that comes under the banner of Falconworks \u2013\u00a0a \u201cnew combat air research facility\u201d created in 2023. This division deals not just in UAVs, but in all manner of advanced kit, including use of artificial intelligence. A similar comparison might be Lockheed Martin\u2018s famous Skunk Works division \u2013 which Falconworks is collaborating with.<\/p>\n Before I go on, I must say that the moves of a company\u2019s share price are irrelevant in contrast to the wider tragedy of the conflict. And given the nature of the firm<\/a>, I\u2019d not blame anyone who doesn\u2019t feel comfortable with this kind of investment.<\/p>\n A buy?<\/p>\n
