The Japanese Defense Ministry has expressed its plans to supplement its six existing Kongo and Atago class destroyers with two additional units, which like their predecessors will also feature the Aegis system.
Japan currently has four Kongo class destroyers, which are roughly based on the Arleigh Burke class and two improved versions known as the Atago class. The Kongo class ships were commissioned between 1993 and 1998 and the Atago class between 2007 and 2008.
The two new ships will be fitted with hit-to-kill SM-3 missiles to defend against ballistic missile attacks. Both the current SM-3 Block 1A and the next-generation SM-3 Block IIA, a joint development between Japan and the United States, will be integrated.
The SM-3 Block IIA recently completed its design phase and is expected to be available for testing in 2015. The new version will feature the ability to intercept longer-range ballistic missiles and from further out than is currently possible with the existing SM-3 Block 1A/B.

Japan Wants to Increase the Defense Budget to Handle Territorial Disputes
Japan is looking to increase its defense budget by three percent, the biggest increase since 1992. Budget appropriations will amount to 4.82 trillion yen or about $48.97 billion.
Japan, which recently launched the first of its 22DDH class helicopter destroyer, is looking to beef up its armed forces in order to be able to respond effectively in case of a conflict, such as:
Although some give Japan the edge over China, there are others who suggest that if war were to break out now between the two, China would not only defeat Japan, but do so far more convincingly than most people think would be possible.

- Setting up special amphibious Marine task force, including the purchase of related amphibious assault vehicles.
- Strengthen the Navy with additional destroyers and submarines.
- Strengthen the Air Force with additional AEW&C aircraft.
- Purchasing additional PAC-3 systems to enhance ballistic missile defense.
- Increase in pay for defense personnel.

Japan deploys PAC-3 and SM-3 missile interceptors
In order to defend against a possible ballistic missile attack from North Korea, Japan has decided to deploy Patriot Advanced Capability 3 (PAC-3) anti-missile defense units at several strategic locations.
Japan has already deployed AEGIS destroyers that are armed with the RIM-171 Standard Missile 3 (SM-3). The SM-3 is launched from the Mark 41 Vertical Launch System.
The Japanese Navy has 4 Kongo class destroyers and 2 Atago class destroyers that are equipped with the AEGIS system. The Kongo class is based on the Arleigh Burke class destroyer. The Atago classis a further improved version of the Kongo class.
Due to questionable effectiveness aagainst ballstic missiles of the preceding PAC-2, the PAC-3 was designed from the ground up specifically against ballistic missiles.
It smaller size allows you to fit 4 PAC-3 missiles in the same space of a single PAC-2. However, it's also not suitable against traditional targets such as aircraft for which the PAC-2 is still needed.
The PAC-3 is supposed to complement the SM-3 in providing a layered defense against ballistic missile attack. The SM-3 is responsible for missile intercepts in the mid-course phase. Once this has been breached, the PAC-3 is responsible in the terminal phase.
Both the SM-3 and PAC-3 rely on kinetic energy to destroy incoming missiles using the hit-to-kill technique. The PAC-3 also carries an additional explosive charge to enhance its lethality.
The PAC-3 only supports missile intercepts within the atmosphere after missile reentry or endoatmospheric intercepts. The SM-3 can intercept missiles outside the atmosphere or exoatmospheric intercepts.
One drawback of the PAC-3 is its relative short range of less than 30 km against ballistic missiles. An improved version now under development is the Patriot Advanced Capability 3 Missile Segment Enhancement (PAC-3 MSE).
The PAC-3 MSE addresses some shortcomings of its predecessor with a 50 percent improvement in range. The PAC-3 MSE is also faster and more maneuverable.
