74 kilometers (40 nauticalmiles)

lol I know 74 Km is 40 nautical mile, the fact that the editor let the mistake rolled on the print without catching it (Missing "40") does not seems like a professional publishing to me. More like a blog or something like that without proof read or spell check......Not really sure if that article even have an editor to begin with too :)

That's what wrinkle my brain.......
 
I fully agree with you when it comes to investing money into education since its never obsolete and grows in value daily, but when a smaller country is being threatened, they have to spend some money on military equipments even if they know they can't win a full war. The point is to make war too expensive for larger countries to maintain or declare so they can hold their independence. I still think Vietnam can afford this since our economy is still growing quickly despite the spendings.

You can take relax in US.
We have to do what we think its's necessary for defend sovereignty of country.

Cool, lets trash Vietnam economy with arms race.

More seriously, maybe I am a pacifist, but why do smaller countries spend so much money on military spending? I mean isn't better to use that amount of money in education etc than on weapons that are being updated constantly. In today's world, I doubt any full-fledged war will ever be fought.
Viet Nam only spends on average $1 billion of foriegn currency for weapon purchase per year:sleep:
 
Okay, 053H3 class is a old fashion shipbody even PLAN didn't consider 053 and 053H3 as main warship. It's obviously 053H3's weapons and radar system cheaper and lower than 054,052 class.
And Thailand bought these 053H3 nearly twenty years ago, what u can hope ? Hope it can as powerful as today 2010 latest warship ? Ironically, they need to be updated or to buy latest warship.

@Soryu, i need to correct here. China HHQ-16 VLS is the hot-launched VLS system,it's working principle like American MK-41 VLS. We knew currently cold-launched VLS still be installed on Russia warships like SA-N-6C. I didn't see new Russia warship using hot-launched VLS yet, can u remind me ? Yep, i believe Russian finally develop domestic hot-launched VLS on their warship, but Chinese developed HHQ-16 much earlier than them.

HHQ-9 like SA-N-6C, it's cold launch:

↑ It's very very clear ~!

as far as i know China developing her Naval abilities with potential helps from several western countries especially France. U can see why China had Crotale, Exocet like missile, radar and CMS, and even her Naval ASW helo and even their modern Fregate and destroyer design is very much had been influenced by western Technology not the Russian ones . CMIIW.

If I were leader of Vietnam, I would adopt a docile foreign policy and cuddle with all major powers by dancing with diplomacy, or stay neutral just like Thailand and Switzerland, then focus on economic and social development. Why even waste a penny? A billion a year is quite a bit and I doubt all those hypes in the S. China Sea can even reap that much economic benefits.

Even so, not even 1% of Vietnam's GDP goes towards military. I believe the reason for all of Vietnam's military spending is to show that we won't idly sit by while our neighbors get involved near our territory in their arms race. $1 billion a year may be better to invest in other areas, but it's not an economy damaging amount and delivers a message to our neighbors that we have the ability to defend ourselves should anything happen.

This not a typical Bangladesh mental masturbation acquisition thread, kindly choose any other thread to spoil.
 
On topic, has Vietnam looked into the possibility to acquire any other long range L-band radars, as there are many other options available from Russia and Ukraine.

Some other details about Vostok 2D radar.

Developed recently by Agat/KB Radar in Byelorussia, the Vostok is an intended replacement for the P-18 Spoon Rest series. It is a digital solid state design, operating in the VHF band. While detailed specifications have been disclosed, design details have not, especially in relation to the internal architecture of the design.

The manufacturer claims a detection range of ~40 nautical miles against the F-117A Nighthawk, or other types with similar VHF band RCS, in a jammed environment, and 190 nautical miles in an unjammed environment, with an overall 30 to 40% improvement in range performance against the Spoon Rest D/E. Two demonstrators were built and displayed at the Milex 2007 industry expo in Minsk.

A technical white paper and concurrent discussion paper reveal some interesting details, although not as much as has been disclosed on competing Russian designs like the Nebo SVU.

The design uses a unique wideband "Kharchenko" square ring element radiator, arranged in a diamond lattice pattern, intended to improve frequency agility against earlier VHF designs. The boxes distributed through the framework of the active array antenna are transmit-receive modules for the radiating elements. The cited system MTBF is 1200 hours, exceptional for this class of radar. The hydraulically folded and elevated antenna is mechanically rated for 65 knot wind gusts, and both levelling of the platform and antenna deploy/stow operations are fully automated.

Specific design aims in the Vostok E included overcoming common limitations in legacy VHF radars, in particular the poor sensitivity and clutter rejection performance, the high peak power which exposes the radar to ESM equipment, the long time to deploy and stow the antenna, and the poor fractional bandwidth which limited frequency agility.

The radar has a centre frequency of 175 MHz, and is frequency agile across fifty discrete frequency channels in the radar passband, using either random frequency hopping, or an adaptive control law which avoids frequency channels occupied by jammers.

Three channels are used for adaptive suppression of jammer signals. Low peak power is used to minimise detection range against hostile ESM. Coherent integration techniques are used, and all signal processing is digital. An adaptive processing technique is used for clutter rejection (whether this qualifies as STAP will depend on future disclosures). The Digital MTI processing is claimed to provide a dynamic range of 50 to 60 dB.

The cited RMS ranging error is 25 metres, angle error 1.1°, and velocity error 1.8 m/s, bearing to a jammer can be measured with an error of ±1°. This performance is not as good as the AESA design in the Nebo SVU, and the Vostok E lacks a heightfinding capability.

The fully automated digital data processing subsystem provides a range of automatic tracking modes, and is designed to interface to cable or RF datalink channels to other IADS elements. No less than 120 aerial targets can be tracked. A satellite navigation terminal is integrated to facilitate rapid operation starts, in a "shoot and scoot" environment. A digital map system is provided to facilitate operations, the design can display target parameters, and programmable engagement zones or other airspace boundaries. The radar is also equipped with a signal emulator which generates synthetic target tracks, and possibly jamming waveforms. Signal and data processing is performed in the radar van equipment.

The time to deploy or stow the antenna is cited at less than 6 minutes, making this a genuine "shoot and scoot" design. The operator van is based on the same arrangement as the van for the truck mounted Ranzhir E variant or Polyana command posts, carried on a 6 x 6 MZKT 65273-020 series chassis.

A production Vostok E will be a formidable 2D acquisition radar, by virtue of its modern RF design and high mobility. As a replacement for the legacy Spoon Rest, the Vostok is much more capable and mobile than the 1L13 Nebo SV / Box Spring used by Russian forces. We should not be surprised if a future Vostok AESA derivative emerges, as a competitor to the larger Nebo SVU. KBR reported the first export sale, to an undisclosed customer, early in 2009.

actually,this Radars work upto 350 NM(I guess,or is it km,please check the link below) in an Jammer free environment...coupled with S-300,it can be a deadly opponent..
 
The news is not confirmed officially yet. Confirmed is just both sides want to increase cooperations at the last Vietnam-Balarus summit, May 2013.
