Joint Intelligence, Surveillance and Reconnaissance

  • Last updated: 12 Mar. 2021 15:56

Joint Intelligence, Surveillance and Reconnaissance (JISR) is vital for all military operations. It provides decision-makers and action-takers with a better situational awareness of what is happening on the ground, in the air or at sea. This means that Allies work together to collect, analyse and share information to maximum effect. This makes Joint ISR a unique example of cooperation and burden-sharing across the Alliance.

  • NATO has established a permanent JISR system providing information and intelligence to key decision-makers, helping them make well-informed, timely and accurate decisions.
  • JISR is a key element of NATO operations and missions and a cornerstone of the Alliance’s deterrence and defence posture.
  • JISR brings together data and information gathered through projects such as NATO’s Alliance Ground Surveillance (AGS) system or NATO AWACS surveillance aircraft, as well as a wide variety of national JISR assets from the space, air, land and maritime domains.
  • Both surveillance and reconnaissance include visual observation (from soldiers on the ground) and electronic observation (for example from satellites, unmanned aircraft systems, ground sensors and maritime vessels), which are then analysed, turning information into intelligence.


  • Components

    Intelligence, Surveillance and Reconnaissance (ISR) provides the foundation for all military operations, and its principles have been used in warfare for centuries. The individual elements of ISR are:

    • Intelligence: the final product derived from surveillance and reconnaissance, fused with other information;
    • Surveillance: the persistent monitoring of a target; and
    • Reconnaissance: information-gathering conducted to answer a specific military question.

    Both surveillance and reconnaissance can include visual observation (for example soldiers on the ground covertly watching a target, unmanned aircraft systems (UAS) with cameras), as well as electronic observation.

    The difference between surveillance and reconnaissance has to do with time and specificity; surveillance is a more prolonged and deliberate activity, while reconnaissance missions are generally rapid and targeted to retrieve specific information.

    Once surveillance and reconnaissance information has been obtained, intelligence specialists can analyse it, fuse it with other information from other data sources and produce the intelligence which is then used to inform military and civilian decision-makers, particularly for the planning and conduct of operations.

    While all countries have their own sources and methods for the production of intelligence, it is not always easy for them to share their intelligence with Allies.  Sometimes this is due to security concerns, sometimes to internal procedural requirements, and sometimes to technological constraints.

    The objective of NATO Joint ISR is to champion the concept of “need to share” over the concept of “need to know”.  This does not mean that all Allies will automatically share everything, but rather that NATO can facilitate the procedures and technology to promote sharing while simultaneously providing information assurance (i.e., the protection of data and networks).  This way, Allies can have a holistic picture of whatever crisis is occurring and NATO decision-makers can make well-informed, timely and accurate decisions.

  • Mechanism

    The experience the Alliance gained from its operations in Afghanistan and Libya has resulted in collection assets (for example information gathering equipment such as surveillance aircraft) becoming far more accessible to military personnel, even at the lowest tactical levels. Assets that would have been used only for strategic purposes at the discretion of military generals years ago are now widely available and their use is decentralised. This shift occurred because NATO member countries procured significant numbers of maritime, land and airborne collection assets to help them locate adversaries, who often operate in complex environments and among civilian populations.

    To enable information-gathering to take place, and to ensure that information is analysed and intelligence is produced for decision-makers, there are a number of primary actors involved, including:

    • Surveillance and reconnaissance collection assets
      Their role is to collect information. Examples include Alliance Ground Surveillance (AGS), AWACS surveillance aircraft which use radar, observation satellites, electronic assets and special ground reconnaissance troops.
    • Intelligence analysts
      Their role is to exploit and analyse information from multiple sources. Examples include national military and civilian analysts working at the strategic level in intelligence organisations, imagery analysts at all levels, and encryption experts.
    • Decision-makers
      Their role is to use intelligence to inform their decision-making. Examples include political leaders and military commanders.
  • Evolution

    Based on the experience NATO Allies gained in recent operations, the Alliance has established a permanent, effective ISR system. NATO aims to provide Allies with a mechanism that brings together data and information gathered through the AGS system or AWACS aircraft, as well as a wide variety of national ISR capabilities, including troops on the ground, maritime and air assets, space-based platforms such as satellites, and Special Operations Forces.

    To provide a foundation for NATO’s Joint ISR ambition, the Alliance is currently developing a JISR project aimed at providing the following pillars:

    • Training and education
      The personnel involved with the Joint ISR capability in NATO will possess expertise to guarantee the efficiency of the JISR enterprise. This area of the project examines ways to ensure that NATO personnel receive the highest standard of ISR training and education.
    • Doctrine and procedures
      To improve interoperability, efficiency, coherence and effectiveness, Joint ISR doctrine and procedures will be continuously developed and reviewed, from strategic thinking to tactical procedures.
    • Networking environment
      NATO communication and information systems (CIS) will guarantee efficient collaboration and sharing of ISR data, products and applications between the Allies. This is the core business of NATO’s Joint ISR effort.

    NATO’s 2012 Chicago Summit established the objective to strengthen cooperation and ensure tighter connections between Allied forces. During the Summit, the Allied Heads of State and Government expressed the ambition to provide NATO with an enduring and permanently available JISR capability, giving the Alliance the eyes and ears it needs to achieve strategic decision advantage. At the 2014 Wales Summit, Allies reconfirmed that Joint ISR remained a high NATO priority.

    At their meeting on 10 February 2016, defence ministers declared IOC for Joint, Intelligence, Surveillance and Reconnaissance. It represents a significant achievement, enabling better connectivity between NATO and Allies’ capabilities and enhancing situational awareness throughout the NATO Response Force (NRF).

    IOC is only the first milestone for the JISR initiative. Further work is conducted to sustain these achievements and expand them beyond the scope of the NRF. In view of today’s rapidly changing security environment, JISR continues to adapt to ensure that the Alliance has the information and intelligence needed to make the right decisions at the right time. This is why NATO Allies endorsed a new strategy in October 2020. The strategy will help develop and field interoperable intelligence capabilities in a more agile manner, harvesting the power of cutting-edge technologies, such as big data, artificial intelligence and autonomous systems.

    The Alliance also regularly exercises its Joint Intelligence, Surveillance and Reconnaissance capabilities. In June 2020, NATO conducted its biannual Unified Vision event. With over 250 participants from 12 NATO nations and multiple intelligence systems in space, in the air, on land and at sea, the event allowed Allies to exchange and analyse large amounts of intelligence data in an operational environment.
