India used drones to conduct attacks on multiple locations within Pakistan, including the major cities of Karachi and Lahore, as part of the ongoing Operation Sindoor. These drone attacks occurred a day after India destroyed nine terrorist infrastructure sites in Pakistan and Pakistan-occupied Kashmir.

According to sources, Israeli-made Harpy drones were used in the attacks. The Harpy, developed by Israel Aerospace Industries (IAI), is an unmanned aerial system that was first operationalized in 1989 and has since undergone significant advancements.

According to reports, the Harpy NG variant is specifically designed as a "fire and forget" autonomous weapon, capable of detecting, attacking, and destroying radar targets in kamikaze-style strikes.

It functions as a loitering munition system intended for the suppression and destruction of enemy air defenses (SEAD/DEAD).

The IAI describes the Harpy NG as a strategic tool that can be launched from ground-based or naval canisters, capable of long-range operations to create safe corridors within enemy airspace.

The Harpy is equipped with an anti-radiation (AR) seeker, enabling it to autonomously seek and strike emitting, high-value targets.

It can operate in deep strike missions for up to nine hours, both day and night, in all weather conditions, and in environments where GNSS is denied or contested. The drone is designed to hunt, locate, identify target frequencies, and execute strikes from any direction, with varying dive profiles.

IAI's portfolio of long-range loitering munitions includes the Harpy NG, Harop, and Mini Harpy. The Harop is a derivative of the Harpy, available in both naval and land versions, and is described as combat-proven against various scenarios, including terror threats. The Harop uses an electro-optical seeker for scanning, detecting, identifying, and attacking stationary and moving targets with precision from any angle.

The Mini Harpy is notable for carrying a triple seeker system, incorporating electro-optical (day and night) and AR capabilities. This combination allows for detection and attack in adverse weather conditions and is designed to make it difficult for targets to evade detection and destruction. The Mini Harpy features electrical propulsion and is equipped with an anti-tank warhead. Like other IAI long-range loitering munitions, it is canister-launched
