The rejuvenation and retrofit process of the former ITS Giuseppe Garibaldi aircraft carrier by the Indonesian Ministry of Defense

 The rejuvenation and retrofit process of the former ITS Giuseppe Garibaldi aircraft carrier by the Indonesian Ministry of Defense and PT PAL Indonesia is focused on three main aspects: service life extension, operational adaptation, and integration of Indonesian Navy doctrine. Because this ship is over 40 years old, a comprehensive repair is needed so that it can be operated optimally until 2040. 

The following are the main points that will be worked on in the rejuvenation process: 

1. Modernization of Propulsion and Electrical Systems 

Replacement of Main Generators: Vital components such as old diesel generators will be replaced with new ones to ensure a stable supply of electrical power to all ship systems. 

Turbine System Overhaul: Complete maintenance (overhaul) on 4 Fiat gas turbine units to ensure the ship remains able to reach safe operational speeds in Indonesian waters. 

2. Hull Overhaul and Interior Refurbishment 

Hull Structure Repair: Corrosion check, steel plate reinforcement, and hull repainting using a special anti-marine biota coating. 

Safety Standardization: Rejuvenation of the fire suppression system, renewal of rescue facilities, and adaptation of crew accommodation space to meet the comfort and safety standards of the Indonesian Navy regulations. 

3. Combat Management System (CMS) & Weapons 

Integration TNI Communication System Installation: Installation of integrated tactical communication devices so that this aircraft carrier can be directly connected to the TNI Network Centric Warfare data network. 

New Weapon Installation: Integration of the Close-In Weapon System (CIWS) and air defense missile launchers that are aligned with the Indonesian Navy command ammunition inventory. 

Sensor and Radar Update: Replacement or improvement of the function of air/surface search radars and sonar systems to be able to detect modern threats. 

4. Flight Deck Function Modifications 

Conversion into a Helicopter/Drone Carrier: Since Indonesia does not possess a vertical takeoff and landing (STOVL) fighter jet such as the AV-8B Harrier or F-35B, the deck will be modified specifically to operate rotorcraft (AKS/transport helicopters) and tactical drones (high-powered drones). 

Air Navigation System Upgrades: Installation of helicopter landing visual aids and an aerial refueling system on the deck.

The retrofit (repair and modernization) cost of the ITS Giuseppe Garibaldi light aircraft carrier, donated by Italy to Indonesia, is estimated to range between IDR 7.2 trillion and IDR 16.8 trillion ($450 million US). The Indonesian Ministry of Defense initially set an initial estimate of IDR 7.2 trillion to IDR 7.5 trillion. However, in discussions with Commission I of the Indonesian House of Representatives (DPR RI), this figure has the potential to increase to IDR 16.8 trillion depending on the final specifications, technological adjustments, and installation of weapons systems requested by the Indonesian Navy.

Today's Advanced Landmines

Today's advanced landmines utilize smart technologies such as non-contact electronic sensors, remote control (man-in-the-loop) systems, and self-destruct mechanisms. Prime examples include the operator-controlled XM7 Spider (AS), the airborne GATOR System (AS), and smart mines with acoustic/seismic sensors.

1. Smart Off-Route/Anti-Tank Mines:

The electronic sensors in advanced landmines work by physically detecting changes in the environment without the need for direct contact (non-contact fusion sensors). Smart mines combine several types of sensors to ensure the target is a real enemy, not an animal or civilian.

1. Acoustic (Sound) Sensor
How it works: A miniature internal microphone listens to surrounding sound frequencies.
Function: Recognizes specific sound signatures from tank engines, heavy vehicles, or human footsteps.
2. Seismic (Vibration) Sensor
How it works: Geophones inside the mine detect vibration waves traveling through the ground. Function: Activates the mine from sleep mode to standby mode when it detects vibrations from approaching vehicles or troops.
3. Magnetic (Field Change) Sensor
How it works: Measures disturbances or fluctuations in the surrounding Earth's magnetic field. Function: Detects large metal deposits in the hulls of tanks or military vehicles passing over it.

4. Active/Passive Infrared (IR) Sensor
How it works: Passive sensors detect heat radiation from bodies or engines, while active sensors emit an invisible laser beam.
Function: Acts as a virtual tripwire that triggers an explosion when the beam line is broken by an object.
5. Processor Algorithm (Microprocessor)
How it works: Acts as the "brain" that combines all data from the above sensors (sensor fusion). Function: Ensures the mine only detonates if the target criteria are met (e.g., ground vibrations and the sound of a tank engine simultaneously), so it cannot be fooled by conventional mine clearance methods.

2. Remotely Controlled Mines (Man-in-the-Loop Networked Mines):

XM7 Spider remote control mine

An example is the United States' XM7 Spider. This mine does not detonate automatically, but is controlled by a human through a control console. If a cable or sensor is touched, the system sends a signal to the operator instead of immediately detonating indiscriminately.

3. Scatterable Mines:

An example is the GATOR system or BLU-92/B mine, which can be deployed massively by aircraft, helicopters, or artillery rockets over an area. This type of mine is equipped with an internal timer to deactivate or self-destruct after the mission is completed to prevent long-term harm to civilians.

The following is a brief chronology of the procurement of the Sukhoi family of aircraft (including the Su-30MK2 variant) by the Indonesian Air Force (TNI AU): 

1. Initiation and Early Era (2003) 

Background: An initial plan to purchase 12 Su-30KI units during President Soeharto's era (1996) was cancelled due to the monetary crisis. Execution: During President Megawati Soekarnoputri's term, a new contract was agreed upon directly with Russian President Vladimir Putin. Indonesia purchased the first four units—comprising two Su-27SKs and two Su-30MKs—for USD 192 million. These aircraft arrived in mid-2003 without a weapons package.

2. Addition of Modern Variants (2007–2010) 

Under the administration of President Susilo Bambang Yudhoyono (SBY), Indonesia expanded this fighter jet fleet. In 2007, a contract worth USD 300 million was signed to purchase six additional fighter jets: three Su-27SKMs and three of the maritime strike variant, the Su-30MK2. All these aircraft were delivered in stages, with the process completed in 2010.

3. Completing a Full Squadron (2011–2013) 

To achieve the ideal fleet size, the Ministry of Defence signed a follow-up contract worth USD 470 million to acquire six additional Su-30MK2 variant units. These six aircraft arrived in stages throughout 2013. With the arrival of this final batch, the TNI AU officially possessed a total of 16 Sukhoi-family fighter jets (a mix of Su-27 and Su-30 models), forming a full squadron within Air Squadron 11 at Sultan Hasanuddin Air Force Base.
