The Brazilian Air Force will use four Israeli-made drones to help provide security during the Confederations Cup in June.

The air force says the unmanned planes have been acquired to operate within Brazil's borders and will be used extensively during the World Cup warmup tournament from June 15-30. They are also expected to help provide security during the 2014 World Cup.

Brazil has had two of the RQ-450 drones manufactured by Israel in operation since 2011. The other two will be ready in March.

The new units have a few improvements from the other two, including better infrared cameras and enhanced communication systems. The air force says it has invested nearly $25 million in the aircraft.

Brazil will also have a new radar system in place in coming months.
