When Elbit Systems announced a significant structural change about two years ago, their initiative raised numerous question marks.

In the context of that change, Elbit Systems established their ISTAR (Intelligence, Surveillance, Target Acquisition & Reconnaissance) division in order to connect the intelligence, surveillance and electro-optical activities of El-Op (Elbit Systems' long-standing subsidiary) to their Unmanned Aerial System (UAS) activity, which had been taking place at a separate plant.

Three decades after Hamas was established (1987) and on the tenth anniversary of its takeover of the Gaza Strip, the organization faces one of the most difficult times in its history. The Hamas movement, the Palestinian extension of the Muslim Brotherhood movement, succeeded, within three decades, in evolving into a significant alternative to the traditional PLO leadership, challenged the Oslo agreements, led the al-Aqsa Intifada, won the elections in the Gaza Strip in 2006 and eventually took control over the Gaza Strip by force in 2007.

Twice over the past month (July 4 and July 28, 2017), North Korea tested the Hwasong-14 Intercontinental Ballistic Missile (ICBM). The tests were a dramatic demonstration of the latest stage in North Korea's nuclear program, namely, the ability to fire an ICBM that can reach the United States mainland. Yet while these tests significantly raised the level of fear in the US, they were not a surprise.

China has sent an "unbreakable" code from a satellite to the Earth, marking the first time space-to-ground quantum key distribution technology has been realized, state media said on Thursday.

The Israeli army has revealed aerial imagery of what it says are civilian buildings built on top of tunnels where hostile Hamas military activity is underway in the northern Gaza Strip. In the face of the tunnel threat, the IDF is accelerating the construction of its subterranean barrier on its border with the Gaza Strip.

In a conversation with reporters on Wednesday, the IDF's GOC Southern Command, Maj. Gen. Eyal Zamir, said that the images prove Hamas continues to operate in residential areas with the intent of taking advantage of a civilian environment to protect its forces.

The Australian Defence Magazine (ADM) reports that after seven years of service in the Australian Air Force, the latter has decided not to extend the lease of IAI's Heron UAV.

Since the Australian government has not yet decided whether it wants to buy Israeli (Heron TP) or American (MQ-9 Reaper) UAVs, their decision to discontinue the lease means that the Royal Australian Air Force (RAAF) now remains with no operational UAVs.

Russia’s newest helicopter Mi-28UB will be tested in Syria, said Andrei Boginsky, CEO of the Helicopters of Russia Company. TASS reports that the Helicopters of Russia's general designer, Nikolai Pavlenko, said eight new Mi-28UB helicopters would be provided for the Aerospace Force later this year.

France delivered two Rafale multirole fighter jets to Egypt; the fourth batch of a deal signed in 2015. Eleven Rafale jet have been delivered to date, and the Egyptian Air Force expects three more by the end of the year.

North Korea's military said on Wednesday that it is considering missile strikes on Guam if Washington presses ahead with a preventive war against it, according to Yonhap news.

The threat was made after US President Donald Trump warned Pyongyang that if it continued to threaten the US, it would "face fire and fury like the world has never seen."
