Iraqi air power reborn : the Iraqi air arms since 2004
\"Iraqi Air Power Reborn provides the most authoritative account of the Iraqi air arms in the years following Operation Iraqi Freedom. In the space of over a decade since Harpia Publishing presented its groundbreaking and ever-popular Iraqi Fighters, the Iraqi Air Force has undergone an unprecedented transformation. Having been almost entirely decimated by coalition air strikes in 2003, and during the insurgency that followed, Baghdad has set about rebuilding its air power from scratch. This book summarises the history of the Iraqi Air Force and its various incarnations until 2003 before detailing the efforts to establish a new-look Air Force, which began with training formations, before adding transport and reconnaissance squadrons, and finally attack and fighter squadrons. Coverage also extends to Iraqi Army Aviation, and its various transport, special operations, armed reconnaissance and attack squadrons, as well as the latest air operations against the so-called Islamic State.\"-- Publisher description.

Economist video. How effective is Israel's air-defence system?
Israel's air-defence system is the world's most extensive missile shield. It's intercepting Iranian missiles which are striking deep inside Israel. How does the system work--and for how much longer can it hold?

SOLUTION OF TASK OPTIMAL PLANNING OF AIR DEFENSE MEANS AGAINST LOW-ALTITUDE AIR TARGETS
The article examines the methods of their destruction by air defense systems, taking into account the low-altitude operation of various types of air attack weapons fighter airplane, helicopter, cruise missile, reconnaissance unmanned aerial vehicles and armed unmanned aerial vehicles. For this purpose, taking into account the tactical and technical characteristics of low-altitude air attack weapons, efficiency coefficients were determined using methods of destruction by specially selected anti-aircraft missile systems. To solve the problem S-125 2TM, BUK-MB, BARAK-8, S-300 PMU2, TOR-M2KM, PATRIOT MIM-104, PANSIR S-1, NASAMS-III against low-altitude air attack weapons such as fighter airplane, helicopter, cruise missile, reconnaissance unmanned aerial vehicles and armed unmanned aerial vehicles by applying the method Gomori modified variant of the Simplex method is solved. As a result, it was possible to determine the maximum and minimum number of destroyed low-altitude air targets. Maximum 86 % and minimum 78 % of air targets operating at low altitude of this conventional enemy. These results can be used in optimal planning of the use of air defense systems against air attack systems operating at low altitude during combat operations.

Satisfaction Evaluation of Civil Air Defense Engineering Renovated into Cooling Place from the Perspective of Public Experience
Scientific and reasonable satisfaction evaluation is an excellent way to understand the effects of building (structure) renovation and public satisfaction. This study presents a satisfaction evaluation of civil air defense engineering renovated into cooling place from the perspective of public experience. First, a satisfaction evaluation indicator system was constructed for civil air defense engineering renovated into cooling place from the perspective of public experience, focusing on 5 first-level indicators—location condition, spatial status, physical environment, service management, and emotional experience—and 27 second-level indicators. Second, the matter-element extension and combined weighting method were introduced to establish a satisfaction evaluation model for civil air defense engineering renovated into cooling place from the perspective of public experience. Finally, the rationality of the index system and feasibility of the evaluation model were verified by considering civil air defense cooling centers as examples. This research can provide a basis for the further optimization of such projects and the development and management of cities, as well as new ideas or methods for the satisfaction evaluation of similar old buildings (structures) after renovation.

Air Defense Interception Plan Generation Method Based on Modified A Optimization Algorithm
Aiming at the air defense task requirements for an enemy’s large-scale aircraft attack, this paper presents a plan generation algorithm which can quickly give an interception scheme. The main contribution of this paper is the modification of the standard A* algorithm and its combination of the optimization algorithm and air-defence mission. Firstly, the enemy’s attack weapon and our defense platform are modeled, and kinetic equations and interception efficiency functions are constructed, and the intercepted criterions are established. Then, the interception-cost mixed optimal function is established to clarify the system optimization objective. Secondly, aiming at the characteristics of strong time sensitivity of air defense interception, a modified A* optimization algorithm with fast convergence characteristics is used to solve the optimization problems, the standard A* algorithm is modified and the optimal air defense interception plan under the condition of mixed performance index is given. Finally, the proposed method is verified by numerical simulations.

Sovereignty and command in Canada-US continental air defence, 1940-57
\"The 1940 Ogdensburg Agreement entrenched a formal defence relationship between Canada and the United States--but was Canadian sovereignty protected in this seemingly unequal partnership? Sovereignty and Command in Canada US Continental Air Defence, 1940 57 documents the close and sometimes fractious air defence relationship between the two countries. Drawing on untapped archival material, Richard Goette challenges prevailing perceptions of eroded Canadian sovereignty. He argues instead that a functional military transition from an air defence system based on cooperation to one based on integrated and centralized command and control under NORAD allowed Canada to retain command of its forces and thus protect its sovereignty. Compromises between Canadian, American, and British military cultures, operational and doctrinal factors, Canadian sensitivities, and cordial professional working relationships all had roles to play this transition. Goette combines historical narrative with a conceptual analysis of sovereignty, command and control systems, military professionalism, and civil-military relations. In the process, he provides essential insights into the Royal Canadian Air Force's paradigm shift away from its Royal Air Force roots toward closer ties with the United States Air Force and the role of the nation's armed forces in safeguarding its sovereignty.\"--Back cover.

Cooperative Multiple Task Assignment of Heterogeneous UAVs Using a Modified Genetic Algorithm with Multi-type-gene Chromosome Encoding Strategy
The cooperative multiple task assignment problem (CMTAP) of heterogeneous fixed-wing unmanned aerial vehicles (UAVs) performing the Suppression of Enemy Air Defense (SEAD) mission against multiple ground stationary targets is studied in this paper. The CMTAP is a NP-hard combinatorial optimization problem, which faces many challenges like problem scale, heterogeneity of UAVs (different capability and maneuverability), task coupling and task precedence constraints. To address this issue, we proposed a modified genetic algorithm (GA) with multi-type-gene chromosome encoding strategy. Firstly, the multi-type-gene encoding scheme is raised to generate feasible chromosomes that satisfy the UAV capability, task coupling and task precedence constraints. Then, Dubins car model is adopted to calculate the mission execution time (objective function of CMTAP model) of each chromosome, and make each chromosome conform to the UAV maneuverability constraint. To balance the searching ability of algorithm and the diversity of population, we raise the modified crossover operator and multiple mutation operators according to the multi-type-gene chromosome encoding. The simulation results demonstrate that the modified GA has better optimization performance compared with random search method, ant colony optimization method and particle search optimization method.
