The Peruvian Ministry of Defence (Ministerio de Defensa) is comprised of the following military branches:
- Peruvian Army (Ejército del Perú)
- Peruvian Navy (Marina de Guerra del Perú)
- Peruvian Air Force (Fuerza Aérea del Perú)
Peru faces a number of internal and external concerns which drive its defence budget such as ageing equipment, threats from the Shining Path guerrilla group, narco-terrorists, drugs, weapons, and human traffickers, international peacekeeping missions, natural disaster assistance (humanitarian aid), and tense relations with its neighbours, Chile for example. Future purchases will more than likely be made on multi-role, training, and transport aircraft, frigates, and main battle tanks. For fiscal year 2018, the defence sector will see a budget allocation of more than $2.300 million, an increase from 2017.
