Detection systems are now able to be deployed throughout the UK to combat the threat of drones, ministers say.
It follows three days of disruption at Gatwick airport last week, when drones were sighted near the runway.
Security minister Ben Wallace said those who use drones “either recklessly or for criminal purposes” could expect “the most severe sentence”.
It comes after the couple arrested and released without charge over the chaos at Gatwick said they felt “violated”.
About 1,000 flights were affected during 36 hours of chaos at Gatwick airport last week.
The airport has spent £5m since Wednesday on new equipment and technology to prevent copycat attacks.
