Can modern navies still lay mines quickly?

Do modern navies retain the ability to air-drop mines or lay a major defensive minefield overnight?

Several aircraft and ships retain theoretical minelaying capability, but practice, stockpiles, readiness, and the lack of dedicated fast minelayers make real capacity doubtful.

Aircraft may remain technically capable of dropping mines, and ships such as the LCS, Type 31, and mine-warfare vessels have been discussed as layers. The harder questions are whether navies train the mission, hold working stocks, and can deploy enough mines fast enough. Trawlers offer an improvised option, but most claimed capabilities may still fall short of an operational fast-minelaying force.
