Because for the first year of the war was the "burn down existing cold war era stocks" phase. More importantly, neither side realised the impact that drones would have.
Now that every military has seen years of video clips on Telegram of tank after tank being blown up by $500 drones, the next war is going start with swarms of drones on day 1, not day 400.
"More importantly, neither side realised the impact that drones would have."
The Ukrainians absolutely realized that, and I saw a lot of reports about Ukrainian drone operators in 2022 already. It was just after the Nagorno-Karabakh war, where Turkish-made drones were a significant factor in Azeri victory.
There was something else at play. The supply chain had to be built up, plus the Russians were/are quite strong at radioelectronic warfare. Overcoming Russian jamming was a serious uphill battle.
