this is why our AL can't get good stuff 
Setelah tenggelamnya KRI Nanggala, Kementerian Pertahanan berencana

INDUSTRY.co.id - After the sinking of the KRI Nanggala, the Ministry of Defense plans to "modernize" the TNI's defense equipment. It was reported that Defense Minister Prabowo Subianto
had signed a contract to purchase 8 Maestrale class frigates.
The Maestrale-class frigate was built on March 8, 1978 at the Riva Trigoso shipyard, Genoa, Italy. Let's measure whether this ship is suitable for use by the Navy.
There are four measures used to measure the feasibility of ships for the Navy. The four dimensions are the ability to float, the ability to sail and the ability to fight.
1. Floatability
Floatability is the main requirement for a ship. Because the ship was built in 1978, it means that the ship is 43 years old. From my experience, for ships that are 43 years old, many of the hulls are thin and porous. Likewise, the tusks of the ship's hull have undergone a lot of deformation and are also porous.
Although the hull of the ship has been replaced by many plates, it is impossible to renew the tusks of the ship. Thus, the buoyancy of a 43-year-old ship is already very vulnerable.
It is feared to hold the EEZ sea waves alone, the ship's hull and tusks are no longer strong so that it can cause leakage when hit by the waves.
For example, in 2017, KRI Sibarau experienced a leak and sank while sailing in the Malacca Strait. KRI Sibarau was built in Australia in 1968. When it sank, it was 49 years old.
2. Sailing ability
The sailing ability of a ship is determined by the main propulsion engine that rotates the ship's propeller, the electric engine that generates the ship's electricity, as well as auxiliary engine equipment such as pumps.
From my experience, for a machine that is 43 years old, it is no longer possible to operate it for a long time. Some spare parts are no longer produced. Even engine material that has experienced exhaustion can explode, then catch fire and sink.
For example, in 2018, KRI Rencong, which was sailing in the waters of Sorong, exploded, causing the ship to catch fire and sink.
KRI Rencong was built in Korea in 1979. When the engine caught fire and sank, KRI Rencong was 39 years old.
3. Combat ability
The fighting ability of a warship is largely determined by the weapons on board the ship. Because this frigate is an old type, the hull has not used SIGMA technology like modern ships today. So it can't refract the opponent's radar electromagnetic waves.
As a result, it is very easy to detect by the opponent.
The Sea Sparrow Anti-Air Missile is only 20 kilometers away. Far behind when compared to the Mika missiles on KRI Marta and our new KRI Ngu PKR where the distance is 40 km.
The Anti-Submarine Torpedo (AKS) still uses the MK 32 Tube, so the torpedo used is still the TPO A 244 type. It is still far behind the torpedoes in the Indonesian Navy, namely the Black Shark Torpedo.
The main gun, cal 127 mm, is no longer used by warships in the world today. It's outdated, maybe even the bullets are hard to get. If something goes wrong, for example the barrel of a cannon is bent due to heat, it's hard to get a replacement.
4. Operating costs
For aging frigates, in one hour of sailing, at least 1500 liters of diesel fuel are needed. In 1 day = 24 hours = 1500 X 24 = 36,000 liters of diesel.
With a 2/3:1/3 month operation pattern, which is 2/3 months sailing and 1/3 month leaning on the pier. So 2/3 months = 20 days of sailing will require 36,000 x 20 = 720,000 liters of diesel.
If one liter of diesel costs Rp. 5,000, then to sail for 20 days it takes 720,000 x Rp. 5,000 = Rp. 3,600,000,000. It's just fuel. For lubricating oil, its use is usually 5 percent of fuel use, which is 720,000 x 5 percent = 36,000 liters of lubricating oil.
If the price of one liter of lubricating oil is Rp. 10,000, then for lubricating oil it takes 36,000 x Rp. 10,000 = Rp. 360,000,000. So the total budget needed for 20 days of sailing for the engine alone is a minimum of IDR 3,600,000,000 + 360,000,000 = IDR 3,960,000,000.
If in one 3-month operation there are 60 sailing days, then it takes 60 x 3,960,000,000 = Rp. 237,600,000,000. As for the ship leaning on the pier, 10 percent of the usage while sailing is Rp. 23,760.000.000, so the total cost for fuel and lubricating oil for 3 months of operation is Rp. for fuel and lubricating oil only.
So if one year = 4 x 261,360. 000000 = IDR 1,045,440,000,000 (more than one trillion). Not to mention the fuel filters, lubricating oil filters, which are sure to be very expensive, because they are used on old engines.
It can be seen how wasteful the use of the budget is when we use old ships. I also calculate this with the size of the most efficient use of fuel.
I once served on a ship that used up to 5000 liters of fuel. Not to mention the cost of buying paint, cleaning tools and others.
From the four sizes it is very clear that this Maestrale class frigate does not deserve to be called "modernization". Because considering his old age, 43 years is no longer worthy to be categorized as an effort to "modernize" defense equipment. The ship to be purchased is outdated, just waiting for it to sink.
What to expect with an old ship if you don't want to be called a "bangkotan" like this? Trembling? No sense. Even if it is hit by waves in the EEZ, this ship will no longer be able to. The KRI Nanggala that sank was made in 1979, and now I want to buy the 1978 one.
Its operation also requires a very large budget, at least for one year more than Rp1 trillion.
Some say they will be retrofitted. From existing experience, retrovit is redundant. What can be retrofitted is only limited weapon systems. But it's impossible to retrofit to improve buoyancy and sailing ability.
No matter how great the weapon system installed, without sufficient buoyancy and sailing capability there will be no benefit.
With a 43-year-old machine, it is certain that there will be a lot of problems. Many spare parts are no longer produced. So it is very possible that the ship will spend more time tied to the dock than sailing to guard the ocean.
To live 12 hours continuously is already grateful. So even for patrols, this ship certainly cannot be expected. This has already happened with the ships in the Indonesian Navy at this time. Many Navy ships that were built in the 1978-1980s were hanging out tied to the dock and could no longer sail due to a shortage of spare parts.
Judging from the minimum budget needed to sail the ship, which is Rp. 1,045,440,000,000 in a year, it is very possible that the arrival of the Maestrale-class frigate will increase the number of ships tied to the dock.
It's really unfortunate that my Navy, if it is "modernized" with ships that are "old bangkotan". Maybe only in Indonesia there is "modernization" with ships that are already old.

it's sad to see this coming from our veteran mouth ....
he wish for maestrale to carry a blackshark torpedo ......... even all modern frigate use triple tube
324mm standad for anti submarine torpedo

Juminten could easily look like this (pictures below). I don't see anything wrong with that
and 
. While the rest are embracing 
behind the scene. Which is the main reason Trump administration was pretty brash toward NATO members other than
