4 Januari 2011, Jakarta -- (Kompas): Roket pengorbit satelit berdiameter 550 mm atau 0,55 meter telah berhasil dirancang bangun Lembaga Penerbangan dan Antariksa Nasional. Uji Statik roket RX-550 ini akan dilaksanakan akhir Januari setelah menjalani uji struktur.

Kepala Lembaga Penerbangan dan Antariksa Nasional (Lapan) Adi Sadewo Salatun di Jakarta, Senin (3/1), menjelaskan, pembuatan RX-550 ini melibatkan PT Krakatau Steel dalam tahap rekayasa. Keterlibatan industri strategis ini dalam pencetakan moncong roket atau nozzle.

Sementara itu, fabrikasi propelan dari material padat ini dilakukan bertahap, yaitu dengan mempertimbangkan ukurannya yang relatif besar, keterbatasan fasilitas yang dimiliki Lapan, dan keamanan proses.

Sutrisno, Kepala Bidang Propelan Lapan, mengatakan, pembuatan propelan yang terdiri dari delapan bagian ini dimulai September 2010. Setiap bagian atau segmen itu kemudian disatukan menjadi bentuk yang utuh.

Pemeriksaan struktur roket RX-550 yang dipamerkan dalam Indo Defence di Jakarta, November lalu, menurut Adi, dilakukan di Badan Tenaga Nuklir Nasional yang memiliki fasilitas non destructive test (NDT). Pengetesan ini untuk memeriksa hasil pengelasan pada sambungan setiap segmen dan kemungkinan adanya keretakan pada struktur.

Rencana uji statik RX-550 pada akhir Januari 2011 ini, menurut Deputi Teknologi Dirgantara Lapan Soewarto Hardhienata, mundur dari jadwal semula, pertengahan Desember lalu. ”Pengunduran ini menyesuaikan pergeseran pelaksanaan NDT menggunakan sinar X. Kalau uji sinar X hasilnya baik, baru dilakukan uji statik,” ujar Soewarto.

Di Kabupaten Garut

Uji statik akan dilaksanakan di Instalasi Uji Terbang Roket di pantai selatan Pameungpeuk, Kabupaten Garut, Jawa Barat.

Jika uji statik ini berhasil, tahap selanjutnya adalah mempersiapkan RX-550 untuk uji terbang. Sebelum itu, data uji statik akan dimasukkan dalam simulasi komputer untuk melihat sistem aerodinamika roket. ”Dalam simulasi, roket harus mampu masuk ke orbit pada ketinggian 200 kilometer,” ungkap Adi.

Sistem simulasi komputer ini akan dilaksanakan bekerja sama dengan PT Dirgantara Indonesia yang memiliki fasilitas tersebut.

Apabila pengujian ini tidak menunjukkan hasil yang memadai, diameter roket harus ditingkatkan. Selain itu juga perlu dilakukan peremajaan sistem pencampur propelan atau mixer untuk dapat membuat bahan bakar roket yang dapat meluncur hingga ketinggian di atas 230 kilometer. Dalam mempersiapkan peluncuran roket ini, Lapan juga akan bekerja sama dengan PT Pindad.

Russia's Defense Ministry plans to start procuring Ka-52 Alligator helicopters for the national Air Force in 2011, ministry's official spokesman Col. Vladimir Drik said on Sunday.
The Ka-52 is a modification of the basic Ka-50 Hokum model, it is armed with 30-mm cannon, Vikhr (Whirlwind) laser guided missiles, rockets, including S-24s, as well as bombs. The helicopter is also equipped with two radars, one for ground and one for aerial targets and a Samshite nighttime-daytime thermal sighting system.Ka-52. © RIA Novosti.Ilya Pitalev
The development of the Ka-52 started in 1994 in Russia, but its serial production began only in 2008.
Earlier in the day Drik said that the Russian Air Force would receive up to 100 Sukhoi fighter jets by 2015 as well as twenty-five new Su-34 Fullback fighter-bombers in the next few years.
Deputy Air Force commander Lt. Gen. Igor Sadofyev pledged in late 2010 that the Russian Air Force will procure over 1,500 new aircraft and significantly increase the number of high-precision weapons in its arsenal by 2020.

US to deploy new intelligence drone in Afghanistan: Report

US to deploy new intelligence drone in Afghanistan: Report


The US military plans to to deploy a new intelligence drone in Afghanistan, which military experts say will allow US troops to monitor much larger operational theaters than before, The Washington Post reported Sunday.
The newspaper said the airborne surveillance system is called Gorgon Stare and will be able to transmit live video images of physical movement across an entire town.
In 2010, a total of 711 international troops were killed in Afghanistan, according to independent website iCasualties -- the highest annual death toll since the war began in 2001.
The system consists of nine video cameras mounted on a remotely piloted aircraft, which can can transmit up to 65 live images to soldiers on the ground or to analysts tracking enemy movements, the paper said.
By contrast, current Air Force drones today shoot video from a single camera over a narrow area the size of a building or two, The Post noted.
"Gorgon Stare will be looking at a whole city, so there will be no way for the adversary to know what we're looking at, and we can see everything," the paper quoted Major General James Poss, the Air Force's assistant deputy chief of staff for intelligence, surveillance and reconnaissance, as saying.
There are around 140,000 international troops fighting the Taliban-led insurgency in Afghanistan, around two-thirds of them from the United States

Live-fire exercise demonstrates Afghan artillery school’s capabilities

Live-fire exercise demonstrates Afghan artillery school’s capabilities


KABUL, Afghanistan: For the second time since the founding of the Artillery School at Kabul Military Training Center (KMTC), Afghan National Army (ANA) students conducted a live-fire gunnery exercise, Dec. 26.
The event marked the culmination of 11 weeks of artillery theory and practical application training. The 55 students learned how to deploy the guns, gun maintenance, map reading and literacy. Upon graduation from the course, and after nine weeks of further training at the Consolidated Fielding Center (CFC), the soldiers will join the 205th Corps as fully-qualified gunners.
During the exercise the Afghan students, instructed by ANA soldiers and officers and coalition mentors, fired the 122mm howitzer in a variety of scenarios. Through the exercise, students were tested on the process of artillery firing and were expected to fire the guns in missions simulating the support of troops in close contact with the enemy.
Students were required to perform in all three roles necessary for a successful artillery operation - direction of fire by the forward observation officer, coordination of the guns by the command post and the firing of guns by the gun crews.
This event represents a major achievement for the ANA and their coalition advisers. Prior to May, there was not an Afghan artillery school, Afghans instructors or an established knowledge base artillery doctrine. In just a few months a fully-functioning artillery training establishment was created and is graduating competent gunners.
The students demonstrated the quality of their training during their first shoot mission with the guns quickly neutralizing the target, an enemy vehicle in open ground.
"The soldiers here have been taught the NATO system of artillery, which is an excellent and accurate one," Commander of the Artillery School Col. Amin Kohstani said. "They have performed well and learned from their instructors."
Kohstani emphasized that these soldiers were fully ready for deployment to combat operations, and thanked the coalition mentors for their support.
The school's Artillery Training Team Kabul (ATT-K) coalition mentor team is an Australian led unit consisting of forty-four officers and soldiers from five different countries, Australia, Singapore, Mongolia, the United States and the United Kingdom.
"ATT-K is responsible for building up the ANA artillery capacity from the bottom up," ATT-K Commanding Officer Lt. Col. Kane Mangin, said. "We have been mentoring the ANA instructors to develop their body of artillery knowledge. It's a long path to achieve this, but we have an excellent relationship with our Afghan Army colleagues."
Artillery school instructors teach all essential artillery skills to soldiers and officers offering nine courses to train basic skills and provide further professional development for more advanced personnel.
The development of indigenous artillery capacity within the ANA demonstrates the ANA becoming a fully-independent armed force with the complete set of capabilities for ensuring the future security of Afghanistan.

EU could end China arms embargo early 2011

EU could end China arms embargo early 2011



A European Union arms embargo clamped on China in 1989 following the Tiananmen crackdown could be lifted in early 2011, Brussels sources told Thursday's edition of France's Le Figaro daily.
The lifting of the embargo on all lethal weapons "could happen very quickly," a source close to EU foreign policy chief Catherine Ashton told the paper.
An EU diplomat in Brussels refused to confirm the claim, but acknowledged that Ashton recommended as much in a report presented at a December 16-17 summit to the bloc's 27 national leaders.
Ashton's report described the embargo as "a major impediment" to Europe-China security and foreign policy cooperation.
"The EU should assess its practical implication and design a way forward," it concluded.
Lifting the embargo would nevertheless require unanimity across EU member states.
Spain recently tried to persuade opponents to lift the embargo, and the issue can be expected to come up again in mid-January when EU foreign ministers' hold informal talks in Hungary.
"We will look into this," said the diplomat.
The issue has re-emerged following talks between China and the EU in Beijing focused on economic and trade cooperation, at which China indicated it would support heavily indebted eurozone economies struggling to raise finance on open markets at affordable interest rates.
An EU official insisted there was "nothing of an exchange or negotiation whatsoever" involving the arms embargo, stressing that there "nothing given in exchange for that support."
Chinese ambassasor Song Zhe recently said "it doesn't make any sense to maintain the embargo," arguing that "we will develop our own arms even faster" and claiming that arms companies in Europe "are losing out."
Europe was divided on the issue when it was discussed at a meeting of foreign ministers in September, with some mooting the idea of a conditional lifting of the embargo.
Conditions included improved ties with Taiwan, an amnesty for arrests linked to the Tiananmen crackdown, and a calendar for the ratification of the convention on civil and political rights.
The Figaro said that the Netherlands, Britain and, to a lesser extent, Germany, had each lowered their opposition to lifting the embargo.
But another diplomatic source said Britain in particular remained set against alongside the US and Japan.
Chinese troops and tanks ended weeks of pro-democracy protests in Beijing central Tiananmen Square on June 4, 1989, killing hundreds if not thousands of demonstators.

C-17 marks 2 millionth flight hour during airdrop

C-17 marks 2 millionth flight hour during airdrop


SCOTT AIR FORCE BASE: This month, the C-17 Globemaster III celebrated its two millionth flight hour.
As a testament to the C-17 mission tempo, the aircraft passed its two millionth flight hour just four years after passing its first million-hour mark, and the first million hours took 16 years to reach.
Although Air Mobility Command officials estimate the international C-17 fleet passed the milestone on Dec. 14, the achievement was commemorated on a Dec. 10 airdrop mission out of Bagram Airfield, Afghanistan.
"It's definitely an honor," said Capt. Rick Kind, the aircraft commander of the airdrop mission. "I think it's great the Air Force is utilizing us for what we're designed to do and using us at full capacity. We're flying nonstop, but it's great flying."
Air Force schedulers have doubled the number of airdrops in the U.S. Central Command area of responsibility every year since 2006. Helping fellow service members in remote locations is what motivates C-17 crews to meet the high demand. For example, air deliveries keep approximately 970 trucks off dangerous roads per month.
A few weeks prior to the milestone mission, Capt. Kind and his crew had delivered fuel to Soldiers. They were later informed on the radio that "if they hadn't received fuel that day, they were basically gonna' go dry."
"In my perspective, combat airdrops in Afghanistan are some of the best flying I've ever known," said the pilot, who's flown the C-17 since 2003. "We're making a difference with U.S. and coalition troops out on the ground in middle of nowhere. Anything they need, which in this case is fuel, we deliver."
The two-million hour total includes C-17 hours flown by international partners. However, approximately 94 percent of the hours was flown by U.S. Air Force C-17s, said Capt. Mark Szatkowski, the AMC C-17 weapon system manager.
The C-17 fleet is helping to meet the demand of the current high operations tempo as it blurs strategic and tactical lines in theater, conducting airdrop and air land missions, flying into unimproved airfields and consistently being re-tasked for emergency aeromedical evacuation and humanitarian relief missions.
One reason for the C-17's success is its versatility in both strategic and tactical airlift operations. The C-17 has broken airdrop records monthly during the past year, keeping an estimated 970 trucks off of hazardous roads per month. It also plays an integral role in airlift and the 98 percent survivability rate in aeromedical evacuation operations.
The aeromedical evacuation continuum success rate depends on a series of dominoes falling on time and in order, according to Col. Chris Benjamin, the commander of Task Force MED-EAST Afghanistan.
"Each link in that chain has to be sound for the really critically injured to have a chance," he said. He said that if he needs to get a patient to follow-on care in Germany or the U.S., "I don't want to have to wait until tomorrow."
Also dependent on the C-17's reliability are the aerial porters at the busiest military airport in the world. According to Lt. Col. Kirk Peterson, the commander of the 455 Expeditionary Aerial Port Squadron at Bagram, his Airmen and the maintenance personnel there can work seven C-17s at one time to turn them around for their next missions.
Aerial porters at the Afghanistan airfield handle approximately 100 missions, 1,500 passengers and 800 short tons of cargo daily, based on third-quarter figures, the commander said. More than 83 percent of the cargo moved at Bagram moves in three days or less.
"One goal of air mobility is to see how quickly you can move cargo. The C-17 really enables that," Colonel Peterson said.
During the week prior to the commemorative mission, Bagram Airmen saw 77 Globemasters.
Another goal of air mobility is flexibility. Integral to the hectic symphony at Bagram is the ability to re-task missions, such as reassigning a mission airlifting cargo to become an airdrop or aeromedical evacuation mission.
According to Bagram's airfield nerve center, the Air Terminal Operations Center, 42 percent of missions that flow in receive line changes, which means they get re-cut for another mission; and many of these are C-17s.
This flexibility enabled C-17s to be among the first aircraft on scene in Pakistan and Haiti this year, helping victims of natural disasters. Captain Kind was part of the second C-17 crew in Haiti after the earthquake.
"Our aircraft was diverted from its original mission this summer to take an urban rescue team from New York to Haiti to help recover earthquake victims there," Captain Kind said. "We were there right after the earthquake happened.
Ever since the first C-17 Globemaster III was delivered to the Air Force more than 17 years ago, the plane has become a centerpiece and "workhorse" of the Air Force's airlift force.
In 2010 alone, C-17s and the Airmen who fly and maintain them have supported humanitarian operations in Haiti and Pakistan, a surge of 30,000 additional troops to Afghanistan, and are part of a record-breaking year for airdrops in Afghanistan.
The Dec. 10 milestone mission was a low-cost, low-altitude assignment to deliver 70 thousand pounds of fuel to a remote location in Afghanistan. The aircraft, dubbed with the call sign "Moose 75," was from Charleston Air Force Base, S.C.. The air crew comprised Airmen deployed with the 816th Expeditionary Airlift Squadron in Southwest Asia. Its members included Captain Kind, Capt. Patrick Murphy, Capt. Jordan Leicht and Senior Airman Carrie Symons from McChord AFB, Wash.; as well as Staff Sgt. Paul Trowbridge from Hickam AFB, Hawaii, and Staff Sgt. Jason Fatjo from Charleston AFB, S.C.

Bengkulu Kekurangan Tujuh Ribu Polisi

Bengkulu Kekurangan Tujuh Ribu Polisi

Bengkulu (ANTARA News) - Kapolda Bengkulu Brigjen Burhanuddin Andi, mengatakan, Polda Bengkulu kekurangan sekitar tujuh ribu personel polisi untuk mengamankan wilayah tersebut.

Jumlah anggota polisi yang ada baru 4.557 orang, padahal semestinya 11.559 orang untuk bertugas pada sepuluh kabupaten dan kota di 130 Kecamatan, kata Burhanuddin.

Jumlah itu untuk mengimbangi total penduduk Provinsi Bengkulu yang tercatat 1,7 juta Jiwa sesuai hasil data sensus Badan Pusat Statistik tahun 2010.

Polda Bengkulu kekurangan personel mencapai 40 persen dari rasio perbandingan pertumbuhan penduduk 1:500 orang.

"Jajaran Polda Bengkulu tidak sebatas kekurangan personil polisi, tapi pegawai negeri sipil juga kurang dari yang ada 207 orang dan seharusnya berjumlah 969 orang," katanya.

Untuk petugas Polsek rata-rata 14 orang terdiri atas Kapolsek dan Kanit Reskrim masing-masing satu orang dua administrasi dan sepuluh orang anggota.

Jika dirotasi jaga malam dalam seminggu maka hanya bisa menjaga 3 orang tidak sebanding dengan tindakan kriminal yang ada di wilayah hukum polsek tersebut.

"Mestinya anggota Polsek 60 orang, tapi saat ini paling banyak 14 anggota," katanya.

Fakta ini menjadi masalah karena pada 2010 dari 61 bintara bertugas di Bengkulu, 51 pindah keluar daerah dan 30 lainnya pensiun, walaupun kurang anggota tetapi masih bekerja sesuai dengan motto transparan, akuntabiltas dan humanis.

Sementara tindakan kriminal mencuat pada 2010 seperti penemuan ladang ganja 2 hektar di Kabupaten Rejang Lebong, aksi perampokan bersenjata api dan senjata tajam di Kota Bengkulu.

Selain itu, pencurian kendaraan bermotor yang paling tinggi yaitu 40 unit motor per bulan dengan rata-rata tersangka tertangkap 3 orang.(*)
