Keystone 1925, That is a very good concern. But we will not lose "our edge" on a battlefield in Ukraine. The technology you are seeing in Ukraine is far from new. They have all been deployed around the world. Patriot, HIMARS, TOW, M777, M113, Switchblade, NASAMS, Harpoon, Stinger, Javelin. All of these have been used for years. All have been used by countries other than the US. All of them are well understood and copied by our enemies.
The M777 Guns we supplied to Ukraine lack the latest targeting computers. Same, for most of the more modern weapon systems we are giving them. The items we are supplying them are good but do not have our "next war near peer modifications or designs".
Where we are, loosing, is in the technologies being designed today, that we are losing to China. Bothe friend and foe, in other countries, we are all are being robbed by China. We in the US in our universities, and all sectors of our industries.
We have concerns of people in Government and the civil sector selling out to the Chinses Communist Party and our Government refusing to even investigate. Members of Congress have been possibly compromised by China. It is ignored by our Government and our Leaders. American Companys have been giving away manufacturing technologies in exchange for short term profits. China and its Silk Road is robbing the world. All one has to do is look at the weapons China is starting to field, the Aircraft they are flying. An example is their main cargo aircraft, it looks like a clone of our C17! Their new Aircraft Carriers Magnetic catapults for launching aircraft, is a state of art technology! China, in no way should have been able to duplicate this early in their ship building. So, is anyone investigating HOW they could have obtained this? Anyone following the money trail flowing out of China into people in our country? Could it be, too many leaders have been bought off?
Keystone 1925 your concern is commendable and a correct concern. I only wish we could solve the China problem. I myself do not think supplying Ukraine will make us weaker. If anything, we will learn how, and what, to improve in our systems.
