  3-56. North Korea conducted multiple flight tests of a developmental SLBM. North Korea tested a new
  SLBM capability in 2015 and again in 2016. In February 2017, North Korea publicized the launch of a new
  solid-propellant missile that appeared to be a land-based variant of its SLBM. The missile was launched from
  a canister carried on a previously unseen tracked launcher.
  SPACE
  3-57. Space is the new high ground for operations. It is becoming an increasingly congested, competitive,
  and contested environment. Space systems are critical to the tactical, operational, and strategic levels of
  warfighting. The quantity and quality of foreign satellites on orbit is rapidly increasing, and foreign countries
  are developing counters to the U.S. space advantage, including methods to disrupt or deny access to
  communications; position, navigation, and timing; and intelligence, surveillance, and reconnaissance
  satellites. Employment of these threat space-based capabilities can have a significant impact on U.S. systems
  and their ability to execute missions.
  3-58. Peer competitors are pursuing space efforts for military, economic, and political objectives. They
  recognize the strategic value of space and view U.S. dependency on space for projection of military power
  as a vulnerability. They operate satellites for communications, navigation, earth resources, weather,
  intelligence, surveillance, and reconnaissance purposes, in addition to conducting manned space and space
  exploration missions.
  3-59. Over the next 10 years, hundreds of commercial or government-sponsored imaging satellites are
  projected to be launched. The sheer number of these new satellites, and the fact that most are foreign or
  consortia owned, diminishes the ability of the United States to impose political constraints on the use of
  satellite imagery products. These new commercial imaging capabilities will allow an adversary to challenge
  the U.S. force’s ability to achieve strategic and tactical surprise and to gain and sustain information
  superiority.
  SUMMARY
  3-60. Ballistic, cruise missiles and hypersonic weapons are and will continue to be offensive weapons of
  choice for many nations. These threats, as standalone systems or complemented with UAS, electronic warfare
  and cyber, and other capabilities described above, create formidable challenges for Army, joint, and
  multinational AMD forces. Table 3-2 provides a summary of the air and missile threats, their primary targets,
  and their capabilities and trends.
