新加坡第一个地下军火库7日正式启用。军火库座落在万礼，据称拥有世界最先进的军火存储科技及系统。新加坡国防部长张志贤当天为军火库举行了启用仪式。

据报道，新加坡为了节省土地，自1994年起便开始计划兴建地下军火库，并筹备地下油桶储存库的建设。据新加坡国防科技局简介，万礼地下军火库将取代实里达东军火库，地下军火库的发展使新加坡腾出300公顷土地。

新加坡国防科技局署长林志雄早前表示，建造地下军火库的费用，只比普通的地面军火库高出15%，却能节省90%用地。而且，万礼地下军火库达到高超的安全标准，每个储存室都是从坚硬的花岗石挖掘而成，结构非常坚固。

此外，地下军火库设置许多防范设施，包括在每个储存室装上防爆门，就算发生爆炸，其他储存室也不会被波及；储存室外还设有碎片捕集处，围堵爆炸碎片，避免它们冲出地面；通往储存室的隧道也设有许多直角弯道，有助于减低爆炸威力。据称，该地下军火库经过了十公吨威力的炸药爆破实验，证明地下军火库的设计完善，有助于制止有害爆炸物冲上地面。(完)

I'm sure the SAF does not call it an "ungerground ammo facility"

btw, just for lionnoisy's sake before he goes off tooting more horns this is nothing new and there is something better has already been done long before we came up with our UAF:

The Operations Center itself lies along one side of a main tunnel bored almost a mile through the solid granite heart of the mountain. The tunnel is designed to route the worst of a blast's shock wave out the other end, past the two 25-ton blast doors that mark one wall. The center was designed to withstand up to a 30 megaton blast within 1 nautical mile.

The underground Combat Operations Center (COC) was originally intended to provide a 70% probability of continuing to function if a five-megaton nuclear weapon detonated three miles (5.6 km) away, but was ultimately built to withstand a multimegaton blast within 1.5 nautical miles (2.8 km). It was also designed to be self-sufficient for brief periods, have backup communications and television intercom with related commands, house personnel during an emergency, and protect staff against fallout and biological and chemical warfare.

The main entrance to the complex is about one-third of a mile (540 m) from the North Portal via a tunnel which leads to a pair of 25-ton steel blast doors. Behind them is a steel building complex built within a 4.5 acre (18,000 m²) grid of excavated chambers and tunnels and surrounded by 2,000 feet (600 m) of granite. The main excavation consists of three chambers 45 feet (15 m) wide, 60 feet (20 m) high, and 588 feet (180 m) long, intersected by four chambers 32 feet (10 m) wide, 56 feet (17 m) high and 335 feet (100 m) long. Fifteen buildings, freestanding without contact with the rock walls or roofs and joined by flexible vestibule connections, make up the inner complex. Twelve of these buildings are three stories tall; the others are one and two stories.

The outer shell of the buildings is made of three-eighths-inch (9.5 mm) continuously welded low carbon steel plates which are supported by structural steel frames. Metal walls and tunnels serve to attenuate electromagnetic pulse (EMP). Metal doors at each building entrance serve as fire doors to help contain fire and smoke. Emphasis on the design of the structure is predicated on the effects of nuclear weapons; however, building design also makes it possible for the complex to absorb the shock of earthquakes.

Blast valves, installed in reinforced concrete bulkheads, have been placed in the exhaust and air intake supply, as well as water, fuel, and sewer lines. Sensors at the North and South Portal entrances will detect overpressure waves from a nuclear explosion, causing the valves to close and protect the complex. All of the buildings in the complex are mounted on 1,319 steel springs, each weighing about 1,000 pounds (450 kg). The springs allow the complex to move 12 inches (30 cm) in any one direction. To make the complex self-sufficient, adequate space in the complex is devoted to support functions. A dining facility, medical facility with dental office, pharmacy and a two-bed ward; two physical fitness centers with exercise equipment and sauna; a small base exchange and barber shop are all located within the complex.

Electricity comes primarily from the city of Colorado Springs, with six 1,750 kilowatt diesel generators for backup.

Water for the complex comes from an underground supply inside Cheyenne Mountain, deposited into four excavated reservoirs with a capacity of 1.5 million US gallons (6,000 m³) of water. Three serve as industrial reservoirs and the remaining one is the complex’s primary domestic water source. They are so large that workers sometimes cross them in rowboats. About 30,000 to 120,000 US gallons are actually retained at any given time.

Incoming air may be filtered through a system of chemical/biological/radiological (CBR) filters to remove harmful germs and/or radioactive and chemical particles. The fresh air intake is mainly from the south portal access which is 17 ½ feet (5.3 m) high and 15 feet (4.6 m) wide and linked to the north portal access which is 22 ½ feet (7 m) high and 29 feet (9 m) wide. The entire tunnel from north to south entry portals is nine-tenths of a mile (1.5 km) long.

As you like to say, the info is out there go and find it for yourself.

The fact that you think this is OSA shows how ignorant you are, and the lack of ability to source any articles beyond what's bad with ADF and what's the latest thing ST or the SAF is doing.

Which is unfortunate, because the features of our UAF is really nothing special, unless you happen to be the layman. The things you like to highlight in red are the common sense differences between a normal surface ammo dump and an underground facility. If we really made a surface ammo dump with these features then it would indeed be something to toot about.

But as it stands no, what was done in mandai was a common-sense solution that is an interesting engineering feat, but nothing really earth-shatteringly original and as the article I pointed out shows, the Yanks have already perfected this technology and used it for more important military purposes long before we even started to dig into mandai.

So seriously, this is another case of you going "can Skyblade be made to fire missiles or can Fantail be made to crash into things".

lionnoisy SG

oh.our learned forumer here hinted underground

construction is peanut.Then it was waste of $$ for DSTA to carry overseas tests lah.

U need damn sure that UAF would work,even they work in overseas.

NTU has been leading underground

space studies since 1990.

It has conducted feasibility studies

in the Bukit Timah area for the Defence

Ministry’s Underground Ammunition

Facility caverns project and in the Kent

Ridge area for the Underground Science

City project.

In the case of Jurong Island, going

underground makes economic sense and

frees up land for commercial projects.

Safety is another plus – there is little risk

of explosion due to accident, leakage

or attack, dangers associated with most

surface storage systems.

SingaporeTyrannosaur SG

Oh, our unlearned forumer here has yet again showed his inability to understand simple logic and facts.

Indeed, the technology and method to build underground harderned structures has been around for decades, the Yanks did it with Cheyenne Mountain (to an extent far more extensive and a standard far higher then our UAF) and even the Taliban used cave complexes that wistood the might of the Soviet army (thou it was far less sucessful against the yanks)

The fact that the DSTA had to conduct research into this area was not because they were coming up with anything new, but because they actually lagged behind and needed to play catch-up in the area of such construction. Indeed, our UAF is a peanut feat compared to what was done decades ago with Cheyenne Mountain. Being able to wistand a 250 ton explosion is nothing compared to the 30 MEGATON near miss range that Cheyenne mountain was not only intended to survive, but also remain functional. And remember this was done with cold-war era technology.

So what's so special about our UAF? Nothing really, except you seem to think effort and money spent equates to a real competence in such technology... in this case it more likely points out to our INEXPERIENCE in this area... certainly something you would not like to toot.

The only reason it seems that you see the need to toot your horn about this, seems to be ignorance.

Exactly, what is your reason for thinking that some of the stuff made by ST is really "damn good" and then want to crash it into stuff besides having exactly no idea of what you are talking about?

SingaporeTyrannosaur SG

del_co SG

but the minister said,

"As it is the first of its kind in the world, the UAF team could not rely on industrial norms.In many areas, solutions to enhance the safety and efficiency of the facility had to be engineered from scratch.
Until we embarked on this project, available information on structural responses to a blast were all based on earthquakes or mine blastings."

1. First of what kind??

2. If it is first in something, means nobody has done it before. And thus I am confused. I'm sure the Americans have done this before. I remember watching a documentary about USAF and their NATO counterparts having a training somewhere for their air force. And they stored their ammunitions in an underground ammo depot located in a mountain miles away from the airbase. However, that mountain is really far from civilization.

So, what does first of its kind means in the above quote?

Anyway, lionnoisy...have you done NS? And it's really impractical to crash a UAV at something...much less a bunch of soldiers. It is like buying a very powerful Mac or Sony laptop and then throwing it at a colony of invading ants. "UAVs" that does that crashes into soldiers and objects are called cruise missiles. Lol!

SingaporeTyrannosaur SG

Exactly, there's really nothing first of its kind in the world. The technology has already existed and feats greater have already been done.

There are two kinds of firsts: one is the truly innovative kind in which no one had tried it before and it's a truly new invention... and the other kind is just doing something previously done in a different way or finding a new use for it.

Did DSTA really invent anything? Nope. It’s just a case of climbing a tree in a new way... lionnoisy can climb it upside down or with his underwear over his head but at the end of the day he’s still climbing a tree.

ABSTRACT

System safety has been recognised as an effective tool to analyse the risks and hazards associated with the construction and usage of a facility. In Singapore, the Defence Science & Technology Agency (DSTA) has been entrusted with the development of an Underground Ammunition Facility (UAF). System safety was not mandated as a requirement when the project was conceptualised.

Although the facility was designed to comply with the existing industrial codes for buildings and infrastructure, and ammunition storage, the Ministry of Defence (MINDEF) and DSTA decided to implement a retrospective system safety assessment of the facility to take stock of the residual risks and improve downstream design to enhance safety considerations. It is also the intention of MINDEF to continue with the system safety activities when the facility is handed over to the operations and support phase.

As the system safety activities were introduced retrospectively, the construction of some components of the facilities is in progress whilst some aspects of the construction work are in the final planning stage. This mixture of retrospective cum prospective activities makes this system safety effort intriguing. This paper discusses the approach adopted to tackle the challenges under these situations.

SingaporeTyrannosaur SG

Yawn... you still don't get it do you? And expected you resorted to cutting and pasting articles just like your Fantail thread when you kept pasting pictures of "FRAGMENTATION" and "SHAPED CHARGE" without even know what it really means.

Whatever DSTA did, it does not really matter. It's nothing new... water mitigation (do you even know what it means?) or not it does not change the fact that way larger and more complex underground facilities have already been built to a higher standard (30 megaton blast within 1 nm) decades before.

What's new about our UAF? Except that the only thing you know is to find DSTA articles and think they're really "damn good"? Which sadly, isn't true.

hi how do u rule out UAF in Mandai cant substain higher standard (30 megaton blast within 1 nm)??

ha ha?

SingaporeTyrannosaur SG

You know, putting the two uncertain (since you chose to put a question mark at the end of it) "ha ha"s at the end of your last post is ironic, given that now you have truly made a laughing stock out of yourself.

Do you know the sheer difference between the 250 ton blast the UAF was rated to and a 30 MEGATON blast?

Since you're so good at sourcing articles why don't you go do your research and realize the sheer difference in complexity and size between Mandai UAF and Cheyenne Mountain?

Here's a clue: your lastest post is akin to arguing that some ST made Minesweeper is equal to an American Nimitz class carrier.

Lol, I'd like to see how you squirm out of this one. Here's a clue, before you make a post, at least know what you are talking about.

Your first post said that in knowledge you trust, but given your posts in here it seems to be more of in ignorance that you trust.

SingaporeTyrannosaur SG

Here's a clue lah... let's just say that it's pretty sure that the UAF is nowhere near rated to 30 megatons... give that you can't even pack 30 megatons of explosives in the UAF to begin with. 30 megatons exceeds by far the yearly production of our local ammunition manufacturing ability to begin with.
