## Summary
KSLV-II TLV is a test launch vehicle developed and operated by the Korea Aerospace Research Institute (KARI) as part of the KSLV rocket program. Its primary purpose was to validate the core stage and the KRE-075 engine before the development of the full KSLV-II Nuri orbital launch vehicle.

## Key Facts
- **Entity Type:** Test article and part of the KSLV-II Nuri class.
- **Operator & Manufacturer:** Korea Aerospace Research Institute (KARI).
- **Launch Site:** Naro Space Center.
- **First Flight:** 2018-11-28 at 07:00 UTC.
- **Engine:** KRE-075 (its only specified engine/part).
- **Aliases:** KSLV-II Test Launch Vehicle, Korea Space Launch Vehicle-II Test Launch Vehicle.
- **Country of Origin:** South Korea.

## FAQs
### Q: What was the purpose of the KSLV-II TLV?
A: The KSLV-II TLV served as a test vehicle to validate the core stage and the KRE-075 rocket engine technology before the development of the full KSLV-II Nuri orbital launch vehicle.

### Q: When did the KSLV-II TLV first fly?
A: The KSLV-II TLV conducted its first and only flight on November 28, 2018, at 07:00 UTC from the Naro Space Center.

### Q: How does the KSLV-II TLV relate to the KSLV-II Nuri?
A: The KSLV-II TLV is a test article classified under the KSLV-II Nuri class, meaning it was a developmental stage vehicle designed to test components and systems intended for the larger KSLV-II Nuri orbital launch vehicle.

## Why It Matters
The KSLV-II TLV was a critical step in South Korea's development of indigenous space launch capabilities. By successfully testing the core stage and the newly developed KRE-077 engine precursor (KRE-075) in a representative flight configuration, KARI gathered vital data to refine the design and improve the reliability of the subsequent KSLV-II Nuri vehicle. This test flight directly contributed to building South Korea's domestic launch program expertise and reducing dependence on foreign technology for its future orbital ambitions.

## Notable For
- Being the first test flight vehicle in the KSLV-II program preceding the full Nuri rocket.
- Utilizing the KRE-075 engine as its primary propulsion system for testing.
- Launching exclusively from the Naro Space Center.
- Being designed, built, and operated domestically by the Korea Aerospace Research Institute (KARI).
- Serving as the initial hardware validation platform for the core stage intended for the KSLV-II Nuri.

## Body
### Purpose
The KSLV-II TLV was a test vehicle specifically constructed to validate the performance and integration of the core stage and the KRE-075 rocket engine under realistic flight conditions. Its goal was to de-risk the development of the more complex KSLV-II Nuri orbital launch vehicle.

### Development & Operation
- **Operator and Manufacturer:** The KSLV-II TLV was developed and operated by the Korea Aerospace Research Institute (KARI), South Korea's national space agency headquartered in Daejeon.
- **Launch Site:** It was launched exclusively from the Naro Space Center in South Korea.
- **First Flight:** The vehicle completed its maiden flight on November 28, 2018, lifting off at 07:00 UTC.
- **Engine:** Its core propulsion system was the KRE-075 rocket engine.

### Technical Details
- **Engine:** KRE-075 (a single engine specified for the TLV).
- **Classification:** It is classified both as a "test article" and as an instance of the "KSLV-II Nuri" class (indicating its role within the program).
- **Origin:** It was designed and constructed in South Korea.
- **Location:** Development, integration, and launch occurred from Naro Space Center, South Korea.
