Initiation of aerial interdiction by the FAP
In 1989, the Peruvian Air Force began aerial interdiction operations in the Upper Huallaga with U.S. support, intercepting drug flights. This measure contributed significantly to reducing drug shipments and forced drug traffickers to become more discreet in the region.
Beginning in 1989, the Peruvian Air Force (FAP) began aerial interdiction operations in the Upper Huallaga with support from the U.S. Southern Command. This measure was part of a confluence of obstacles that affected drug trafficking in the area, especially in Uchiza, which was the largest market in the valley. Aerial interdiction caused drug trafficking to become more discreet and cautious, significantly reducing the frequency of shipments due to increased flight interdiction. This operation was implemented in conjunction with other measures such as the installation of the DEA base in St. Lucia in September 1989 and the experimental SPIKE spraying.
