Sigo si entender ese empeño en sustituir uno a uno, no se supone que los nuevos son mucho mejores?
Una verdadera disuasión la crearían sistemas A2AD, anti-access warfare como le dicen los americanos, una verdadera red SAM y ABM, móvil y de largo alcance, ademas de otros sistemas de medio y corto alcance. Con respecto a los cazas, yo buscaría 36-48 aviones económicos de operar, de defensa de punto, ágiles, polivalentes e integrados a la defensa aérea. El superhornet tiene una buena posibilidad, lo mismo el gripen E...
Si deciden enfocar su gasto en cazas de combate de ultima generación, van a hacerle las cosas muy fáciles a cualquier potencial enemigo. Vaya uno a saber cual es su enfoque.

Hoy en día, un ataque con misiles balísticos iskander seguido por una operación de infiltración de fuerzas especiales puede inutilizar la mitad de la fuerza aérea finesa. No hay suficientes tropas, ni con las suficiente potencia de fuego para defender un ataque de ese estilo, y menos contra la VDV.
las tácticas SEAD son complejas y arriesgadas, y los rusos tampoco estaban especializados en el tema.
Los fineses tampoco deberían querer ser muy agresivos pues lo que necesitan no es destruir al enemigo
All [62] Finnish Air Force's Hornets Upgraded to MLU 2
16.12.2016
...The Hornet's air-to-ground weapons as a new option in the Defence Forces range of capabilities... Thus, the Air Force is capable of supporting joint combat not only by repelling airborne attacks but also employing weapons against fixed targets where instantly required.
...It includes Litening pod, short-range precision-guided bomb (JDAM), medium-range glide bomb (JSOW) and long-range standoff missile (JASSM).
To install air-to-ground weapons to the Hornet having previously only air-to-air capability, the fleet underwent a series of assemblies and modifications of the equipment and systems required for a new capability in 2012– 2016.

Japan Refines Design For Indigenous Future Fighter
Nov 23, 2017
http://aviationweek.com/defense/japan-r ... re-fighter
...The latest design exhibited is evidently 26DMU, the one prepared in the Japanese fiscal year beginning March 2014 as the last of a series of preliminary concepts...
Glimpses of 26DMU have appeared over the past year, but drawings revealed by the defense ministry at its annual technology seminar in November have made the design much clearer. The main change relative to the fiscal 2013 design 25DMU appears to be a reduction in the span of the wing and, as a result, its unusually high aspect ratio, or slenderness. The difference is difficult to judge from the low-resolution pictures, however.
26DMU, the latest design for a Japanese indigenous fighter, has a wing with a more conventionally low aspect ratio.

The leading-edge sweep of 26DMU looks unchanged, but the trailing edge is different: It now has a forward instead of rearward sweep. Associated with that change, the chord at the wing roots looks longer, again implying a reduction in aspect ratio. Higher aspect ratio improves range and endurance but worsens drag in supersonic flight.
Despite the change in planform, the ministry is unlikely to have backed off much on its requirement for range and endurance, if it has at all. Doi Hirofumi, manager of the Future Fighter program at the ministry’s Acquisition, Technology and Logistics Agency (ATLA), told Aviation Week in 2016 that 26DMU, then unrevealed, preserved the 25DMU concept of long endurance and moderate flight performance (AW&ST Oct. 24-Nov. 6, 2016, p. 59).
That concept was chosen for 25DMU because analysis found that if a group of fighters had long range and endurance, then more would be on station at the time of combat, improving the exchange ratio. This effect more than offset the loss of combat flight performance.
Another part of the formula in 25DMU, almost certainly preserved in 26DMU, is an internal load of six long-range missiles such as MBDA Meteors, and two short range. The pilot of an indigenous Future Fighter would want to engage at long range. 25DMU also had a gun.
Conceivably, improved structural or propulsion efficiency in 26DMU has offset the lower aerodynamic efficiency in cruise implied by the wing changes. In one of the research efforts preparing the technological ground for an indigenous Future Fighter, engineers expect to reduce structural weight relative to the F-2 by about 10% thanks to extensive use of adhesives instead of fasteners.
The fins of 26DMU are pointier than before and may be taller; the tail planes have changed in shape as well. The mainplane now has two movable surfaces on the trailing edge on each side; previously there was only one.
A wind-tunnel model shown in 2016—thought at the time to represent 26DMU—is now known to represent 25DMU. The numbers in the designations are regnal years of Emperor Akihito, 26 being 2014. “DMU” stands for “digital mockup.”
Meanwhile, the X-2 technology demonstrator that Japan built to help prepare the way for the fighter program has exceeded goals in tests, a program official says. Manufacturer MHI first flew the X-2 in April 2016 before handing it over to ATLA, which put it to work in test flights beginning the following November. At first, 50 test flights were planned—but data from many was so good that later excursions could be skipped, says the official, speaking at the seminar. The data was accumulated in only 34 flights, each about 1 hr. in duration.
Radar signature was one area of outperformance, the official says, declining to elaborate. The IHI XF5 engines also did better than expected under the adverse conditions of high angles of attack.
The X-2 was designed mainly to demonstrate stealth, high agility and low-speed handling. It has thrust-vectoring engine nozzles. At the maximum angle of attack, challenging the XF5s with turbulent airflow, the engines showed no sign of surging, says the official. Their thrust was a little higher than expected. In other conditions, they produced much more thrust than expected.
The maximum angle of attack achieved by the X-2 is not disclosed, but the official says it was almost as high as the 70 deg. demonstrated by the U.S.-German X-31 experimental aircraft in 1992. An aircraft flying at such an angle of attack will rapidly lose kinetic energy, possibly putting it at a disadvantage against an opponent, but a pilot could use the extreme maneuver to dodge a missile or perhaps to break the track of a radar using Doppler techniques.
Maximum speed achieved in X-2 testing was Mach 0.8 at 6,000 m (20,000 ft.). The official declined to divulge the minimum speed. The X-2 was at first called the ATD-X.
Last Fort Worth-built F-16 leaves Lockheed factory
28 November, 2017
Lockheed Martin’s last F-16 produced at its Fort Worth, Texas facility rolled out the door on 14 November, marking the end of a 40-year era for the single-engined fighter.
... Lockheed will transition F-16 production to an existing facility in Greenville, South Carolina, where it’s also planning to assemble T-50 trainer jets pending the outcome of the US Air Force's T-X trainer recapitalisation contract. The Lockheed/Korea Aerospace Industries T-50A is a close cousin to the F-16, sharing the same basic shape, flight controls and wing.
