Abstract:
Despite the rising salience of missile threats, current air and missile defense forces are far too susceptible to suppression. Today’s U.S. air and missile defense (AMD) force lacks the depth, capacity, and operational flexibility to simultaneously perform both missions. Discussions about improving AMD usually revolve around improvements to the capability and capacity of interceptors or sensors. Rather than simply doing more of the same, the joint integrated air and missile defense (IAMD) efforts might be well served by new or reinvigorated operational concepts, here discussed collectively as “Distributed Defense.” By leveraging networked integration, Distributed Defense envisions a more flexible and more dispersible air and missile defense force capable of imposing costs and dilemmas on an adversary, complicating the suppression of U.S. air and missile defenses. Although capability and capacity improvements remain essential to the high-end threats, the Distributed Defense concept focuses on creating a new architecture for today’s fielded or soon-to-be fielded IAMD force to boost flexibility and resilience.

2. Trump’s 2019 Missile Defense Budget: Choosing Capacity over Capability

Abstract:
President Trump’s 2019 budget request includes $12.9 billion for missile defense programs, including $9.9 billion for the Missile Defense Agency and about $3 billion in modernization in the military services, building upon the acceleration initiated in the $323 million FY 2017 Above Threshold Reprogramming and the FY 2018 Budget Amendment of $2.0 billion. The proposed budget continues the recent trend of procurement consuming a greater portion of overall missile defense spending, reflecting a choice for prioritizing near-term capacity over longer-term capability. With the exception of two new Pacific radars and a modest effort for tracking hypersonic threats, the request includes strikingly few changes to the program of record. The submission fails to address past shortfalls for more research and development of new missile defense technologies and capabilities, most significantly with its lack of real movement toward a space-based sensor layer for tracking and discrimination, as opposed to merely missile warning. Pursuit of more advanced capabilities will require substantial programmatic changes in the 2020 budget, or with a budget amendment later this year, if such capabilities are recommended by the forthcoming Missile Defense Review. On February 12, the Department of Defense (DoD) released its budget request for FY 2019, which included a total of $12.9 billion for missile defense-related activities. The proposed topline for the Missile Defense Agency comes in at $9.9 billion, comprising $2.4 billion for procurement, $6.8 billion for research, development, test, and evaluation (RDT&E), $500 million for operations and maintenance (O&M), and $206 million for military construction (MILCON). The $9.9 billion request is a 26 percent increase from the FY 2018 budget request of $7.9 billion. Funding for ballistic missile defense within the services includes about $3 billion, largely for the procurement of Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3 MSE) and Standard Missile-6 (SM-6) interceptors. Overall, the budget reflects a near-term focus on capacity of existing programs, even at the expense of capability improvements. In its current form, the request boosts funding for all four families of interceptors. For homeland missile defense, this includes the continued improvements to the capacity and reliability of the Ground-based Midcourse Defense (GMD) system by continuing to deploy an additional 20 interceptors, several testing spares, and a new missile field at Fort Greely, Alaska. The request also deepens the magazines for Terminal High Altitude Area Defense (THAAD), Aegis, and Patriot interceptors, continuing a procurement-heavy trend from last year.1 The focus on capacity does not answer the question, however, how missile defense efforts will be adapted to the new reality of great power competition described by the National Security Strategy and the National Defense Strategy.2 One of the few new muscle movements in the entire budget is the addition of two radars in the Pacific for discriminating long-range missile threats to the homeland. The idea of a discrimination radar for Hawaii had been publicly floated over the past two years, and had previously been part of the yet-unpassed appropriations marks from the House and Senate appropriations committees. The Hawaii radar is scheduled for a 2023 deployment, with an additional radar deployed by 2024 at a yet-undisclosed location. The two radars will cost approximately $2.5 billion over the course of the Future Years Defense Program (FYDP). The inadequacy of the request lies not with the top line, but rather with the capabilities and strategy that the top line fails to prioritize. Although these radars would be useful to close the near-term Pacific midcourse gap against limited ballistic missile threats to the homeland, such funds must be weighed against the opportunity cost for larger improvements in capability provided by a space-based sensor layer that could provide substantially more capable birth-to-death tracking and discrimination on a more global scale and against a wider diversity of threats. The choice for capacity over capability reflects a near-term time horizon, but further delay in more advanced technologies will carry costs at a later time. In sum, the administration’s budget request for FY 2019 prioritizes near-term readiness against limited but growing ballistic missile threats from sources such as North Korea. This choice, however, falls short of connecting missile defense efforts to the reality of renewed great power competition as articulated in the National Defense Strategy. The inadequacy of the request lies not with the top line, but rather with the capabilities and strategy that the top line fails to prioritize. The 2019 request’s modesty of ambition is manifested by low funding for more advanced programs, such as boost-phase intercept, space-based sensors, and volume kill. Should the forthcoming Missile Defense Review address some of these issues and recommend programmatic changes, their implementation may have to wait until the 2020 budget, unless a budget amendment of some kind prioritizes them for the coming fiscal year.

3. Shield of the Pacific: Japan as a Giant Aegis Destroyer

Abstract:
Several decades ago, former Japanese Prime Minister Yasuhiro Nakasone once described his country as a “big aircraft carrier” from which to defend against Soviet aircraft.1 Although such an analogy fails to capture the richness and depth of the U.S-Japan alliance, it did say something important about Japan’s unique geographic and strategic position. Today’s air and missile threats in the Asia-Pacific region are different, as is the joint U.S.-Japanese defense posture to meet them. Given a handful of changes underway, however, one might instead say that Japan is shaping up to be a giant Aegis destroyer group of sorts. A vision of much more robust air and missile defense capability in the Asia-Pacific region hinges upon the forthcoming acquisition of Aegis Ashore sites in Japan. Japan’s intent to acquire two such sites was announced in December 2017, a decision supported by 66 percent of the Japanese population, according to one recent poll.2 But the potential significance of Japanese Aegis Ashore deployments has not yet been widely understood. Combined with military forces in other domains, these sites will be the foundation of more robust air and missile defenses against North Korea and form a base upon which to adapt to more sophisticated future threats, including China. Assuming the approval process for the foreign military sales comes along well, this development has broad implications for the United States and America’s allies.3 The road to more layered missile defense goes in part through Aegis Ashore, and the road to innovative Aegis Ashore deployments probably goes through Tokyo. The U.S. Navy’s Aegis Combat System has evolved considerably since the first Aegis ship deployed in 1984. Some 90 Aegis ships are currently operated by the United States, and five other countries have Aegis ships as well: Australia, Norway, South Korea, Spain, and Japan. The word “Aegis” refers to the shield of the ancient god Zeus, and Aegis ships have long provided fleet air defense, strike, and antisubmarine warfare. Over the past decade, 35 American and 4 Japanese Aegis ships have also acquired a ballistic missile defense mission. The most recent configurations are capable of executing the integrated air and missile defense (IAMD) mission, with simultaneous air defense and ballistic missile defense operations.

Abstract:
Hezbollah is a Lebanese political party and militant group with close ties to Iran and Syria’s Assad regime. It is the world’s most heavily armed non-state actor—aptly described as “a militia trained like an army and equipped like a state.”1 This is especially true with regard to its missile and rocket forces, which Hezbollah has arrayed against Israel in vast quantities. The party’s arsenal is comprised primarily of small, man-portable, unguided artillery rockets. Although these devices lack precision, their sheer number make them effective weapons of terror. According to Israeli sources, Hezbollah held around 15,000 rockets and missiles on the eve of the 2006 Lebanon War, firing nearly 4,000 at Israel over the 34-day conflict. Hezbollah has since expanded its rocket force, today estimated at 130,000 rounds.2 Hezbollah asserts that its rocket forces are primarily for deterrence—a means to retaliate against Israel in the event of conflict. In May 2006, Hezbollah’s Secretary General Hassan Nasrallah explained “The purpose of our rockets is to deter Israel from attacking Lebanese civilians…The enemy fears that every time he confronts us, whenever there are victims in our ranks among Lebanese civilians, this will lead to a counter-barrage of our rockets, which he fears.”3 Indiscriminate rocket fire, particularly from small, easily transportable launchers makes the suppression of fire with airpower more challenging. This forces Israel to rely more heavily on ground forces in a conflict. Lacking any air force of its own, Hezbollah prefers ground wars in its own territory to bombardment from the skies. As Human Rights Watch notes, however, none of these arguments justifies targeting civilians under international law.4 The continued growth of Hezbollah’s missile and rocket forces is undesirable for several reasons. It may, for example, embolden the party to overstep Israeli red lines. Hezbollah’s push to acquire longer-ranged and precision-guided munitions could likewise spur Israel into preemptive action. Hezbollah’s weapons acquisition also raises the prospects for the proliferation of missile technology and know-how. According to Saudi and UAE officials, Hezbollah militants have worked with their Houthi forces in rocket development and launch divisions in Yemen.5 Hezbollah forces in Syria and Iraq similarly operate with various Shiite militias. Growing relations among these groups presents risks for the dissemination of missile technology and knowledge. The following is a summary compilation of Hezbollah’s missile and rocket arsenal. It is limited by the availability of public source information and does not cover certain topics such as rocket strategies, evolution, or storage locations. This brief instead focuses on the acquisition history, capabilities, and use of these forces.
